Dual Universal Switched-Capacitor Filters
General Description
The MAX7490/MAX7491 consist of two identical lowpower, low-voltage, wide dynamic range, Rail-to-Rail®, 2nd-order switched-capacitor building blocks. Each of the two filter sections, together with two to four external resistors, can generate all standard 2nd-order functions: bandpass, lowpass, highpass, and notch (band reject). Three of these functions are simultaneously available. Fourth-order filters can be obtained by cascading the two 2nd-order filter sections. Similarly, higher order filters can easily be created by cascading multiple MAX7490/MAX7491s. Two clocking options are available: self-clocking (through the use of an external capacitor) or external clocking for tighter cutoff frequency control. The clockto-center frequency ratio is 100:1. Sampling is done at twice the clock frequency, further separating the cutoff frequency and Nyquist frequency. The MAX7490/MAX7491 have an internal rail splitter that establishes a precise common voltage needed for single-supply operation. The MAX7490 operates from a single +5V supply and the MAX7491 operates from a single +3V supply. Both devices feature a low-power shutdown mode and come in a 16-pin QSOP package.

General DescriptionThe MAX2605–MAX2609 evaluation kits (EV kits) simplify evaluation of this family of voltage-controlled oscillators (VCOs). These kits enable testing of the devices’ per-formance and require no additional support circuitry.Both signal outputs use SMA connectors to facilitate connection to RF test equipment.These EV kits are fully assembled and tested. Their oscil-lation frequencies are set to approximately the midrange of the respective VCOs.Featureso Easy Evaluationo Complete, Tunable VCO Test Board with Tank Circuit o Low Phase Noiseo Fully Assembled and TestedEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits19-1673 Rev 0; 9/00Ordering InformationComponent SuppliersFor free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.MAX2606 Component ListMAX2605 Component ListE v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 2_______________________________________________________________________________________Quick StartThe MAX2605–MAX2609 evaluation kits are fully assembled and factory tested. Follow the instructions in the Connections a nd Setup section for proper device evaluation.Test Equipment Required•Low-noise power supplies (these are recommended for oscillator noise measurement). Noise or ripple will frequency-modulate the oscillator and cause spectral spreading. Batteries can be used in place of power supplies, if necessary.– Use a DC power supply capable of supplying +2.7V to +5.5V. Alternatively, use two or three 1.5V batteries.– Use a DC power supply capable of supplying +0.4V to +2.4V, continuously variable, for TUNE.Alternatively, use two 1.5V batteries with a resistive voltage divider or potentiometer.•An RF spectrum analyzer that covers the operating frequency range of the MAX2605–MAX2609• A 50Ωcoaxial cable with SMA connectors •An ammeter (optional)Connections and Setup1)Connect a DC supply (preset to +3V) to the V CC and GND terminals (through an ammeter, if desired) on the EV kit.2)Turn on the DC supply.

Generally, the VCC pin on the PC board should have a decoupling capacitor placed close to the IC. This minimizes noisecoupling from the supply. Also, place the VCO as far away as possible from the noisy section of a larger sys-tem, such as a switching regulator or digital circuits.The VCO ’s performance is strongly dependent on the availability of the external tuning inductor. For best per-formance, use high-Q components and choose their val-ues carefully. To minimize the effects of parasitic ele-ments, which degrade circuit performance, place the tuning inductor and C BYP close to the VCO. For higher-frequency versions, include the parasitic PC board inductance and capacitance when calculating the oscillation frequency. In addition, remove the ground plane around and under the tuning inductor to minimize the effect of parasitic capacitance.Noise on TUNE translates into FM noise on the outputs;therefore, keep the trace between TUNE and the control circuitry as short as possible. If necessary, use an RC filter to further suppress noise, as done on the EV kits.E v a l u a t e : M A X 2605–M A X 2609MAX2605–MAX2609 Evaluation Kits 4_______________________________________________________________________________________Figure 2.

MAX8510 MAX8511 MAX8512 极低噪声、低掉电的线性调压器说明说明书
General DescriptionThe MAX8510/MAX8511/MAX8512 ultra-low-noise, low-dropout (LDO) linear regulators are designed to deliver up to 120mA continuous output current. These regulators achieve a low 120mV dropout for 120mA load current. The MAX8510 uses an advanced architecture to achieve ultra-low output voltage noise of 11μV RMS and PSRR of 54dB at 100kHz.The MAX8511 does not require a bypass capacitor, hence achieving the smallest PC board area. The MAX8512’s output voltage can be adjusted with an external divider.The MAX8510/MAX8511 are preset to a variety of voltag-es in the 1.5V to 4.5V range. Designed with a P-channel MOSFET series pass transistor, the MAX8510/MAX8511/MAX8512 maintain very low ground current (40μA).The regulators are designed and optimized to work with low-value, low-cost ceramic capacitors. The MAX8510 requires only 1μF (typ) of output capacitance for stability with any load. When disabled, current consumption drops to below 1μA.Package options include a 5-pin SC70 and a tiny 2mm x 2mm x 0.8mm TDFN package.Applications●Cellular and Cordless Phones ●PDA and Palmtop Computers ●Base Stations●Bluetooth Portable Radios and Accessories ●Wireless LANs ●Digital Cameras ●Personal Stereos●Portable and Battery-Powered EquipmentFeatures●Space-Saving SC70 and TDFN (2mm x 2mm) Packages ●11μV RMS Output Noise at 100Hz to 100kHzBandwidth (MAX8510)●78dB PSRR at 1kHz (MAX8510) ●120mV Dropout at 120mA Load●Stable with 1μF Ceramic Capacitor for Any Load ●Guaranteed 120mA Output●Only Need Input and Output Capacitors (MAX8511) ●Output Voltages: 1.5V, 1.8V, 2.5V, 2.6V, 2.7V, 2.8V,2.85V, 3V,3.3V,4.5V (MAX8510/MAX8511) and Adjustable (MAX8512) ●Low 40μA Ground Current ●Excellent Load/Line Transient●Overcurrent and Thermal Protection19-2732; Rev 5; 5/19Output Voltage Selector Guide appears at end of data sheet.Ordering Information continued at end of data sheet.*xy is the output voltage code (see Output Voltage Selector Guide).

The parts are available with preset output voltages ranging from 1.5V to 4.5V in 100mV increments. These devices can supply loads up to 120mA. As shown in the Functional Diagram , the MAX8510/MAX8511 consist of an innovative bandgap core and noise bypass circuit, error amplifier, P-channel pass transistor, and internal feedback voltage-divider. The MAX8512 allows for adjustable output with an external feedback network.The 1.225V bandgap reference is connected to the error amplifier’s inverting input. The error amplifier compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the refer-ence voltage, the pass-transistor gate is pulled low. This allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass transistor gate is pulled high, allowing less cur-rent to pass to the output. The output voltage is fed back through an internal resistor voltage-divider connected to the OUT pin.An external bypass capacitor connected to BP (MAX8510) reduces noise at the output. Additional blocks include a current limiter, thermal sensor, and shutdown logic.Internal P-Channel Pass TransistorThe MAX8510/MAX8511/MAX8512 feature a 1Ω (typ) P-channel MOSFET pass transistor. This provides sev-eral advantages over similar designs using a PNP pass transistor, including longer battery life. The P-channel MOSFET requires no base drive, which considerably reduces quiescent current. PNP-based regulators waste considerable current in dropout when the pass transistor saturates. They also use high base-drive current under heavy loads. The MAX8510/MAX8511/MAX8512 do not suffer from these problems and consume only 40μA of quiescent current in light load and 220μA in dropout (see the Typical Operating Characteristics ).Output Voltage SelectionThe MAX8510/MAX8511 are supplied with factory-set output voltages from 1.5V to 4.5V, in 100mV increments (see Ordering Information ). The MAX8512 features a user-adjustable output through an external feedback net-work (see the Typical Operating Circuits ).To set the output of the MAX8512, use the following equa-tion:OUT REF V R1R2X -1V=where R2 is chosen to be less than 240kΩ and V REF = 1.225V. Use 1% or better resistors.PINNAMEFUNCTIONMAX8510MAX8511MAX8512SC70TDFN -EP SC70TDFN -EP SC70TDFN -EP 151515IN Unregulated Input Supply 232323GNDGround343434SHDN Shutdown.

Driving SHDN low disables the voltage reference, error amplifier, gate-drive circuitry, and pass transistor (see the Functional Diagram), and the device output enters a high-impedance state. Connect SHDN to IN for normal operation.Current LimitThe MAX8510/MAX8511/MAX8512 include a current lim-iter, which monitors and controls the pass transistor’s gate voltage, limiting the output current to 200mA. For design purposes, consider the current limit to be 130mA (min) to 300mA (max). The output can be shorted to ground for an indefinite amount of time without damaging the part. Thermal-Overload ProtectionThermal-overload protection limits total power dissipation in the MAX8510/MAX8511/MAX8512. When the junction temperature exceeds T J = +160°C, the thermal sensor signals the shutdown logic, turning off the pass transis-tor and allowing the IC to cool down. The thermal sensor turns the pass transistor on again after the IC’s junction temperature drops by 10°C, resulting in a pulsed output during continuous thermal-overload conditions.Thermal-overload protection is designed to protect the MAX8510/MAX8511/MAX8512 in the event of a fault con-dition. For continual operation, do not exceed the abso-lute maximum junction temperature rating of T J = +150°C. Operating Region and Power DissipationThe MAX8510/MAX8511/MAX8512 maximum power dis-sipation depends on the thermal resistance of the case and circuit board, the temperature difference between the die junction and ambient, and the rate of airflow. The power dissipation across the device is:P = I OUT (V IN - V OUT)The maximum power dissipation is:P MAX = (T J - T A) / (θJC + θCA)where T J - T A is the temperature difference between the MAX8510/MAX8511/MAX8512 die junction and the sur-rounding air, θJC is the thermal resistance of the package, and θCA is the thermal resistance through the PC board, copper traces, and other materials to the surrounding air. The GND pin of the MAX8510/MAX8511/MAX8512 per-forms the dual function of providing an electrical connec-tion to ground and channeling heat away. Connect the GND pin to ground using a large pad or ground plane.Noise ReductionFor the MAX8510, an external 0.01μF bypass capaci-tor between BP and OUT with innovative noise bypass scheme reduces output noises dramatically, exhibiting 11μV RMS of output voltage noise with C BP = 0.01μF and C OUT = 1μF. Startup time is minimized by a poweron cir-cuit that precharges the bypass capacitor. Applications InformationCapacitor Selectionand Regulator StabilityUse a 1μF capacitor on the MAX8510/MAX8511/MAX8512 input and a 1μF capacitor on the output. Larger input capacitor values and lower ESRs provide better noise rejection and line-transient response. Reduce output noise and improve load-transient response, stability, and power-supply rejection by using large output capacitors. Note that some ceramic dielectrics exhibit large capaci-tance and ESR variation with temperature. With dielec-trics such as Z5U and Y5V, it may be necessary to use a 2.2μF or larger output capacitor to ensure stability at temperatures below -10°C. With X7R or X5R dielectrics, 1μF is sufficient at all operating temperatures. A graph of the region of stable C OUT ESR vs. load current is shown in the Typical Operating Characteristics.Use a 0.01μF bypass capacitor at BP (MAX8510) for low-output voltage noise. The leakage current going into the BP pin should be less than 10nA. Increasing the capaci-tance slightly decreases the output noise. Values above 0.1μF and below 0.001μF are not recommended. Noise, PSRR, and Transient ResponseThe MAX8510/MAX8511/MAX8512 are designed to deliv-er ultra-low noise and high PSRR, as well as low dropout and low quiescent currents in battery-powered systems. The MAX8510 power-supply rejection is 78dB at 1kHz and 54dB at 100kHz. The MAX8511/MAX8512 PSRR is 72dB at 1kHz and 46dB at 100kHz (see the Power-Supply Rejection Ratio vs. Frequency graph in the Typical Operating Characteristics).When operating from sources other than batteries, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors, and through passive filter-ing techniques. The Typical Operating Characteristics show the MAX8510/MAX8511/MAX8512 line- and load-transient responses.MAX8512Low-Dropout, 120mA Linear RegulatorsDropout VoltageA regulator’s minimum dropout voltage determines the lowest usable supply voltage. In battery-powered sys-tems, this determines the useful end-of-life battery volt-age. Because the MAX8510/MAX8511/MAX8512 use aP-channel MOSFET pass transistor, their dropout voltage is a function of drain-to-source on-resistance (RDS(ON)) multiplied by the load current (see the Typical Operating Characteristics ).MAX8512Low-Dropout, 120mA Linear RegulatorsFunctional Diagram*xy is the output voltage code (see Output Voltage Selector Guide).

BATTERY MANAGEMENT Jul 09, 1998 Switch-Mode Battery Charger Delivers 5AThe fast-charge controller IC3 (Figure 1) normally directs current to the battery via an external pnp transistor. In this circuit, the transistor is replaced with a 5A switching regulator (IC1) that delivers equivalent power with higher efficiency.Figure 1. By controlling the PWM duty cycle of switching regulator IC1, the fast-charge controller (IC3) makes efficient delivery of the battery's charging current.IC1 is a 5A buck switching regulator whose output is configured as a current source. Its internal power switch (an npn transistor) is relatively efficient because V CE(SAT) is small in comparison with the 15V-to-40V inputs. (For applications that require 2A or less, the low-saturation, non-Darlington power switch of a MAX726 offers better efficiency.)R6 senses the battery-charging current and enables IC3 to generate an analog drive signal at DRV. The signal is first attenuated by the op amp to assure stability by reducing gain in the control loop. It then drives IC1's compensation pin (VC), which gives direct access to the internal PWM comparator. IC3 thus controls the charging current via the PWM duty cycle of IC1. The Q1 buffer provides current to the DRV input.Loop stability is also determined by the feedback loop's dominant pole, set by C4 at the CC terminal of IC3. If you increase the value of the battery filter capacitor (C5), you should make a proportional increase in the value of C4. Lower values, however, assure good transient response. If your application produces load transients during the fast-charge cycle, check the worst-case response to a load step. To assure proper termination of the charge, battery voltage should settle within 2msec to 5mV times N (where N is the number of battery cells).

When V CC falls below the reset threshold, RESET goes low and holds the µP in reset for 140ms min after V CC rises above the threshold.The RESET output is guaranteed to be in the correct state with V CC down to 1V. The MAX709 provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +5V, +3.3V, or +3V powered systems. The MAX709 is available 8-pin DIP, µMAX, and SO packages._______________________ApplicationsMinimum Component Count, Low-Cost Processor Systems___________________________Featureso +5V, +3.3V, and +3V Versions o No External Components o Low Costo Precise Power-Down Reset Threshold o 140ms Min Power-On Reset Delay o Immune to Short Negative V CC Transients o 8-Pin DIP, µMAX, and SO Packages o Low Supply Current: 35µA - MAX709R/S/T65µA - MAX709L/M______________Ordering Information* Dice are specified at T A = +25°C ,DC parameters only.Note:This part offers a choice of five different reset thresholdvoltages.

The graph was generated using a negative-going pulse applied to V CC , starting 1.5V above the actual reset threshold and ending below it by the magnitude indicated (reset comparator over-drive). The graph indicates the typical maximum pulse width that a negative-going V CC transient may have without causing a reset pulse to be issued. As the magnitude of the transient increases (goes farther below the reset threshold), the maximum allowable pulse width decreases. Typically, for the MAX709L/MAX709M, a V CC transient that goes 100mV below the reset threshold and lasts 40µs or less will not cause a reset pulse to be issued.A 0.1µF bypass capacitor mounted as close as possible to pin 2 (V CC ) provides additional transient immunity.Ensuring a Valid RESET OutputDown to V CC = 0VWhen V CC falls below 1V, the MAX709 RESET output no longer sinks current—it becomes an open circuit.Therefore, high-impedance CMOS logic inputs con-nected to the RESET output can drift to undermined voltages. This presents no problem in most applica-tions, since most µP and other circuitry is inoperative with V CC below 1V. However, in applications where the RESET output must be valid down to 0V, adding a pull-down resistor to the RESET pin will cause any stray leakage currents to flow to ground, holding RESET low (see Figure 2). The resistance value of R1 is not criti-cal. It should be about 100k Ω, which is large enough not to load RESET and small enough to pull RESET to ground.____________________Pin DescriptionFigure 1.Maximum Transient Duration without Causing aReset Pulse vs. Reset Comparator OverdriveMAX709Power-Supply Monitor with Reset_______________________________________________________________________________________5Interfacing to µPs with Bidirectional Reset PinsMicroprocessors with bidirectional reset pins (such as the Motorola 68HC11 series) can contend with the MAX709 reset output. If, for example the MAX709RESET output is asserted high and the µP wants to pull it low, indeterminate logic levels may result. To correct this, connect a 4.7k Ωresistor between the MAX709RESET output and the µP reset I/O (see Figure 3).Buffer the MAX709 RESET output to other system com-ponents.CCFigure 3.Interfacing to µPs with Bidirectional Reset I/OM A X 709Power-Supply Monitor with ResetMAX709Power-Supply Monitor with Reset_______________________________________________________________________________________7RESETVCCGND0.045" (1.143mm)0.056" (1.422mm)___________________Chip Topography________________________________________________________Package InformationTRANSISTOR COUNT: 380SUBSTRATE CONNECTED TO V CCMaxim cannot assume responsibility for use of any circuitry other than circuitry entirely embodied in a Maxim product.

Functional Diagram appears at end of data sheet.
The MAX197 multi-range, 12-bit data-acquisition system (DAS) requires only a single +5V supply for operation, yet accepts signals at its analog inputs that may span both above the power-supply rail and below ground. This system provides 8 analog input channels that are independently software programmable for a variety of ranges: ±10V, ±5V, 0V to +10V, or 0V to +5V. This increases effective dynamic range to 14 bits, and provides the user flexibility to interface 4mA-to-20mA, ±12V, and ±15V powered sensors to a single +5V system. In addition, the converter is overvoltage tolerant to ±16.5V; a fault condition on any channel does not affect the conversion result of the selected channel. Other features include a 5MHz bandwidth track/hold, a 100ksps throughput rate, software-selectable internal or external clock and acquisition, 8+4 parallel interface, and an internal 4.096V or an external reference. A hardware SHDN pin and two programmable powerdown modes (STBYPD, FULLPD) are provided for lowcurrent shutdown between conversions. In STBYPD mode, the reference buffer remains active, eliminating start-up delays. The MAX197 employs a standard microprocessor (µP) interface. A three-state data I/O port is configured to operate with 8-bit data buses, and data-access and bus-release timing specifications are compatible with most popular µPs. All logic inputs and outputs are TTL/CMOS compatible. The MAX197 is available in 28-pin DIP, wide SO, SSOP, and ceramic SB packages. For a different combination of ranges (±4V, ±2V, 0V to 4V, 0V to 2V), refer to the MAX199 data sheet. For 12-bit bus interface, refer to the MAX196 and MAX198 data sheets.
Agilent 11970系列混合器数据手册说明书
Agilent 11970 Series Harmonic MixersData Sheet For use with the Agilent E4407B, 8560E/EC Series, 8566B,71000 Series, and PSA Series spectrum analyzers,plus the N9030A PXA signal analyzerExceptional performanceThe Agilent Technologies 11970 Series harmonic mixers are general purpose mixers employing a dual-diode design to achieve very flat frequency response and lowconversion loss. Each mixer is calibrated across its full band:11970K* 18 to 26.5 GHz 11970A 26.5 to 40 GHz11970Q 33 to 50 GHz 11970U 40 to 60 GHz11970V 50 to 75 GHz 11970W 75 to 110 GHzThis series of mixers has been designed for a local oscillator frequency of 3 to 6.1 GHz. Accurate absolute amplitude measurements can be made by using the mixer’s conversion loss calibration chart. The SWR of the waveguide input is typically 2.2:1 to further minimize measurement uncertainty. The combination of high gain-compression level and low conversion loss provides the maximum dynamic range for measuring input signals.* 11970K is excluded from PXA support18 to 110 GHz11970K*, 11970A, 11970Q, 11970U, 11970V, 11970W19812Easy to useThe excellent frequency response and low conversionloss are achieved without external dc bias or tuning stubs. Since bias and tuning stubs are not required, manualoperation is simplified, and the complexity of hardware and software for automatic systems is greatly reduced. The repeatability of amplitude measurements is also enhanced. The dual-diode design of the mixers further simplifiesmeasurements by suppressing the odd-order harmonics by more than 20 dB, which makes identification of the mixing products easier.RuggedThe rugged Agilent 11970 Series mixers willsurvive input levels up to 100 milliwatts (+20 dBm)with no damage to the mixer diodes. They will withstand shocks up to 30 G’s and the vibration required by MIL-STD 28800C, Type III, Class 3 tests.Figure 1. The 11970 Series mixers have separate LO input and IF output portsAgilent 8560E/EC Series spectrum analyzer Extended frequency 8560E/ECSeriesFrequency extension for the Agilent E4407B,8560E/EC Series, 8566B, and 71000 Series and PSA Series spectrum analyzersThe 11970 Series harmonic mixers are fully compatiblewith the Agilent E4407B, 8560E/EC Series, 8566B (requires a preamplifier), 71000, and PSA Series spectrum analyzers. Accurate frequency and amplitude measurements are made directly from the spectrum analyzer’s display after calibration using the mixer’s calibration chart.Frequency extension for the Agilent N9030A PXA Series signal analyzerThe 11970 Series harmonic mixers (11970K excluded) are also compatible with the N9030A PXA Series high-performance signal analyzer. The PXA offers optional external mixing (Option EXM), enabling it to work with the 11970 Series and other external mixers for frequency extension. An external diplexer is required because the PXA external mixing has a single SMA LO/IF port, whereas the 11970 Series mixers have separate LO and IF ports. Recommended diplexers can be purchased from Agilentas N9020A-E13, or from OML Inc. as DLP.313B.Spectrum analyzerExtended frequency PSA SeriesAgilent E4407B spectrum analyzer Extended frequency E4407B ESA-E SeriesAgilent N9030APXA Series signal analyzer Extended frequency PXA Seriesharmonic mixer3Input frequency, GHzNominal frequency response & conversion loss1826.533 40 50 60 75 110C o n v e r s i o n l o s s , d B50454035302520KAQUVWSpecificationsSpecifications describe the device’s warranted performance over the temperature range 0 to 55° C (except where noted).11970 Series tested with Agilent PSA spectrum analyzersAgilent model number Frequency range (GHz) LOharmonic number Maximum conversion loss (dB) Nominal spectrum analyzer noise (dBm)1 kHz BW Frequency response (dB) Nominal gain compression (dBm)11970K 18 to 26.56– 24 –105 ±1.9 –311970A 26.5 to 40 8– 26 –102 ±1.9 –511970Q 33 to 50 10– 28 –101 ±1.9 –711970U 40 to 60 10– 28 –101 ±1.9 –711970V 50 to 75 14– 40 –92 ±2.1 –311970W75 to 11018–46–85±3.0–1Nominal performance, as noted in the following tables, while not warranted, provides information useful in applying the device.1.

python中solution类与maxdepth方法
python中solution类与maxdepth方法摘要：1.Python中的Solution类2.Solution类的maxdepth方法3.使用maxdepth方法优化解决方案4.实例分析5.总结与建议正文：在Python中，Solution类通常用于解决复杂问题，它可以帮助我们将问题分解为更小的部分，并实现高效的解决方案。
Solution类的maxdepth方法则是一种优化技术，它可以限制解决方案的深度，从而提高算法的效率。
**1.Python中的Solution类**Solution类是一个泛指，它可以代表任何解决复杂问题的类。
在Python 中，我们可以自定义一个Solution类，用于封装问题的解决方案。
通过继承和多态，我们可以针对不同的问题设计相应的Solution子类。
**2.Solution类的maxdepth方法**maxdepth方法是一种优化技术，用于限制解决方案的深度。
在递归算法中，maxdepth可以防止栈溢出，提高程序的稳定性。
maxdepth方法接收一个整数参数，表示允许的最大深度。
在实现maxdepth方法时，我们需要判断当前解决方案的深度是否超过最大深度，如果超过，则返回一个错误提示，否则继续执行解决方案。
**3.使用maxdepth方法优化解决方案**在实际应用中，我们可以通过以下步骤使用maxdepth方法优化解决方案：1.分析问题，确定合适的递归策略。
2.设计Solution类，并实现maxdepth方法。
3.在递归过程中，调用maxdepth方法，判断当前深度是否超过最大深度。
4.如果超过最大深度，返回错误提示或采取其他策略，如回溯、剪枝等。
5.如果没有超过最大深度，继续执行解决方案。
**4.实例分析**以八皇后问题为例，我们可以设计一个Solution类并实现maxdepth方法来优化解决方案：```pythonclass Solution:def maxdepth(self, n: int) -> int:if n <= 1:return 0return 1 + max(self.maxdepth(i) for i in range(1, n + 1) if self.check(n, i))def check(self, n: int, i: int) -> bool:for j in range(n):if i == j or i == n - j - 1:continueif self.check(n - 1, j) and self.check(n - 1, i - j):return Truereturn Falsedef solveNQueens(self, n: int) -> List[List[str]]:self.res = []self.max_depth = self.maxdepth(n)self.dfs(0, 0, n, self.res)return self.resdef dfs(self, row: int, col: int, n: int, res: List[List[str]]) -> None: if row == n:res.append(["".join(item) for item in self.board])returnfor i in range(n):if self.check(n, i):self.board[row][i] = "Q"self.dfs(row + 1, i + 1, n, res)self.board[row][i] = "."def board = [[None] * n for _ in range(n)]**5.总结与建议**在解决复杂问题时，使用Solution类和maxdepth方法可以提高算法的可读性和实用性。

Dual, 8-Bit, 60Msps, 3V, Low-Power ADC with Internal Reference and Parallel Outputs
General Description
The MAX1197 is a 3V, dual, 8-bit analog-to-digital converter (ADC) featuring fully differential wideband trackand-hold (T/H) inputs, driving two ADCs. The MAX1197 is optimized for low-power, small size, and high-dynamic performance for applications in imaging, instrumentation and digital communications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 120mW while delivering a typical signal-to-noise and distortion (SINAD) of 48.5dB at an input frequency of 30MHz and a sampling rate of 60Msps. The T/H-driven input stages incorporate 400MHz (-3dB) input amplifiers. The converters may also be operated with singleended inputs. In addition to low operating power, the MAX1197 features a 3mA sleep mode as well as a 0.1µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of this internal or an externally applied reference, if desired, for applications requiring increased accuracy or a different input voltage range. The MAX1197 features parallel, CMOS-compatible threestate outputs. The digital output format can be set to two’s complement or straight offset binary through a single control pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing with various logic families. The MAX1197 is available in a 7mm x 7mm, 48-pin TQFP package, and is specified for the extended industrial (-40°C to +85°C) temperature range. Pin-compatible lower and higher speed versions of the MAX1197 are also available. Refer to the MAX1195 data sheet for 40Msps and the MAX1198 data sheet for 100Msps. In addition to these speed grades, this family will include a multiplexed output version (MAX1196, 40Msps), for which digital data is presented time interleaved and on a single, parallel 8-bit output port. For a 10-bit, pin-compatible upgrade, refer to the MAX1182 data sheet. With the N.C. pins of the MAX1197 internally pulled down to ground, this ADC becomes a drop-in replacement for the MAX1182. o Single 2.7V to 3.6V Operation o Excellent Dynamic Performance 48.5dB/45.3dB SINAD at fIN = 30MHz/200MHz 69dBc/53.5dBc SFDR at fIN = 30MHz/200MHz o -72dB Interchannel Crosstalk at fIN = 20MHz o Low Power 120mW (Normal Operation) 9mW (Sleep Mode) 0.3µW (Shutdown Mode) o 0.05dB Gain and ±0.05° Phase Matching o Wide ±1VP-P Differential Analog Input Voltage Range o 400MHz -3dB Input Bandwidth o On-Chip 2.048V Precision Bandgap Reference o User-Selectable Output Format—Two’s Complement or Offset Binary o Pin-Compatible 8-Bit and 10-Bit Upgrades Available
