MAX2605-MAX2609中文资料
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. If used, the ammeter readingMAX2607 Component ListMAX2608 Component ListEvaluate: MAX2605–MAX2609MAX2605–MAX2609 Evaluation Kits_______________________________________________________________________________________3approximates the typical operating current specified in the MAX2605–MAX2609 data sheet.3)Connect the VCO output (OUT+ or OUT-) to a spec-trum analyzer with a 50Ωcoaxial cable.4)Apply a positive variable DC voltage between 0.4V and 2.4V to TUNE.5)Check the tuning bandwidth on the spectrum analyz-er by varying the tuning voltage (+0.4V to +2.4V).Layout ConsiderationsThe EV kit PC board can serve as a guide for laying out a board using the MAX2605–MAX2609. 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.

MAX232中文资料及应用
MAX232中文资料及应用一.max232资料简介该产品是由德州仪器公司（TI）推出的一款兼容RS232标准的芯片。
由于电脑串口rs232电平是-10v +10v，而一般的单片机应用系统的信号电压是ttl电平0 +5v,max232就是用来进行电平转换的,该器件包含2驱动器、2接收器和一个电压发生器电路提供TIA/EIA-232-F电平。
该器件符合TIA/EIA-232-F标准，每一个接收器将TIA/EIA-232-F电平转换成5-V TTL/CMOS电平。
每一个发送器将TTL/CMOS电平转换成TIA/EIA-232-F电平。
主要特点1、单5V电源工作2、 LinBiCMOSTM工艺技术3、两个驱动器及两个接收器4、±30V输入电平5、低电源电流：典型值是8mA6、符合甚至优于ANSI标准 EIA/TIA-232-E及ITU推荐标准V.287、ESD保护大于MIL-STD-883（方法3015）标准的2000V下图为MX232双串口的连接图，可以分别接单片机的串行通信口或者实验板的其它串行通信接口：三.max232应用电路，注意电容接法。
232是电荷泵芯片，可以完成两路TTL/RS-232电平的转换，它的的9、10、11、12引脚是TTL电平端，用来连接单片机的。
制作at89s51单片机器编程器的电路图MAX232获得正负电源的另一种方法在单片机控制系统中，我们时常要用到数/模（D/A）或者模/数(A/D)变换以及其它的模拟接口电路，这里面要经常用到正负电源，例如： 9V,-9V; 12V,-12V.这些电源仅仅作为数字和模拟控制转换接口部件的小功率电源。
在控制板上，我们有的只是5V电源，可又有很多方法获得非5V电源。
1.外接；2.DC-DC变换......在这里我介绍一块大家常用的芯片：MAX232. MAX232是TTL--RS232电平转换的典型芯片，按照芯片的推荐电路，取振荡电容为uF的时候，若输入为5V,输出可以达到-14V左右，输入为0V ,输出可以达到14V,在扇出电流为20mA的时候，处处电压可以稳定在 12V和-12V.因此，在功耗不是很大的情况下，可以将MAX232的输出信号经稳压块后作电源使用。

Figure 图 3.详细的串行接口时序图
数字输入 数字输入与 CMOS 逻辑兼容。当通过 0.3 ✕ VDD 和 0.7 ✕ VDD 之间的过渡区切换逻辑 输入时，电源电流稍微增加。 微处理器接口 MAX5222 串行接口与 Microwire、SPI 和 QSPI 兼容。对于 SPI，清除 CPOL 和 CPHA 位 （CPOL=0 和 CPHA=0）。cpol=0 将非活动时 钟状态设置为零，CPHA=0 更改 SCLK 下降沿 的数据。此设置允许 SPI 以全时钟速度运行。 如果您的祄 P 上没有串行端口，则可以使用 并行端口的 3 位逐位模拟串行端口操作。只 有在必要时才操作串行时钟，从而使电压输 出处的数字馈通最小化。

It’s perfect for coarse chopping and fine too when done at a higher speed. You can make tomato coarse puree as well. I grate my carrots which are perfect for my salad and sandwiches. Like Report housemanager 3 years ago Also consider a stick blender for mixing cooked foods, like soups, as the cleanup process is easier and faster than for a food processor.

Like Share More 2 answers housemanager 6 years ago This is an old model so it may be difficult to find. There are a couple of used ones currently listed for sale or via auction on ebay in the USA you would need to use an adaptor and in the UK only the base motor is listed so you would need to buy parts and accessories. The postage may be expensive. Most parts and accessories are still listed for sale on ebay and the internet and the instruction manual is also still available online. However, it may be cheaper to buy a more recent model. I may sell mine in a few years to buy a new food processor. Like Report Kirra21 4 years ago When were these released.

数字电位器max5402中文资料
Max5402的H脚与L脚之间包含255个串联的固定电阻。
可调端（W引脚)可以通过编程连到任意一个抽头上。
Max5402具有SPI兼容的三线串行数据接口，这个只写（write-only)的接口包含三个输入：片选（CS非），数据in（DIN），和数据时钟（SCLK）。
当CS非是低时，在每一个SCLK脉冲的上升沿（图1），Din脚出来的数据同步的装载到8位串行移位寄存器。
MSB先移动，如图3所示。
注意，如果CS非在全部数据流期间没有一直保持低电平，数据将被破坏，需要重新下载。
当8位数据全部装载到移位寄存器后，一旦CS非为高电平，数据立即锁存到解码器。
解码器使电位器抽头移动到8bit输入数据对应的位置。
对于max5402，每一个电阻单元是10KΩ/256,即39..2Ω。
Max5402具有POR电路特性。
当上电时，通过将二进制数128移到锁存器，电位器抽头处于
中间位置。
将W连接到H或L，可以当作可变电阻。

1MSM9552/MSM9553¡ SemiconductorGENERAL DESCRIPTIONThe MSM9552 and MSM9553 are LSI devices which demodulate FM character multiplex signals in the DARC (DAta Radio Channel)* format to acquire digital data. The MSM9552 and MSM9553operate on 5V and 3V, respectively. In the DARC format, baseband signals at ordinary FM broadcasting frequencies are multiplexed with 16k-bps digital data which are L-MSK-modulated at 76kHz.Each of the MSM9552 and MSM9553 has a bandpass filter consisting of SCF, frame synchroniza-tion circuit, error correction circuit, etc. on a single chip.So, a system for acquisition of digital data can be easily constructed by externally mounting an FM receiver tuner, microcontroller for control, and memory for temporary storage of data.The MSM9552 and MSM9553 have a simple configuration, and are equipped with only necessary functions. By making changes to software for the external microcontroller, the MSM9552 and MSM9553 can meet the various requirements of FM multiplex broadcasting services which will be offered in future.These LSI devices are best suited to the radio sets and information devices for FM character multiplex broadcasting, which started in Japan in October 1994. Especially, the MSM9553 is suitable for portable units.* DARC is a registered trademark of NHK ENGINEERING SERVICES, INC.Note that a contract needs to be made with NHK Engineering Service if a manufacturer produces/sells electronic equipment utilizing the DARC technology.FEATURES•Built-in bandpass filter (SCF)•Built-in block synchronization circuit and frame synchronization circuit •Setting of the number of synchronization protecting stages •Regeneration of data clocks by digital PLL •1T delay detection•Built-in error correction circuit•Built-in layer 4 and layer 2 CRC check circuit •Microcontroller parallel interface•Clock output for external devices (64kHz to 8.192MHz selectable)•International standard frame format •Power source:5V (MSM9552), 3V (MSM9553)•Package44-pin plastic QFP (QFP44-P-910-0.80-2K)¡ Semiconductor MSM9552/MSM9553LSI for FM Multiplex Data DemodulationMSM9552/MSM9553 2BLOCK DIAGRAMData bus DB0-DB7AddressAD0-AD5CSWRRD CLRXTAL1XTAL2XOUT INT¡ Semiconductor3MSM9552/MSM9553¡ Semiconductor 44-Pin Plastic QFPNote:Leave the NC pins open.PIN CONFIGURATION (TOP VIEW)A0XOUT CS XTAL2XTAL1DV DD DGND DB7DB6DB5DB4D B 3D B 2D B 1D B 0R DN CW RI N TM O U T 6M O U T 5M O U T 4MON ADETIN AV DD AGND SG A IN XOUTC MOUT0MOUT1MOUT2MOUT3A 1A 2A 3A 4A 5N CC L RI O R DI O W RN CN C¡ SemiconductorMSM9552/MSM95534PIN DESCRIPTIONFunction Symbol Pin Type DescriptionMicro-controller interfaceWR 16I Write signal to internal register RD 18I Read signal to internal registerINT 15O Interrupt signal to microcontroller.

MAX5842MEUB+中文资料
General DescriptionThe MAX5842 is a quad, 12-bit voltage-output, digital-to-analog converter (DAC) with an I 2C ™-compatible, 2-wire interface that operates at clock rates up to 400kHz. The device operates from a single 2.7V to 5.5V supply and draws only 230µA at V DD = 3.6V. A power-down mode decreases current consumption to less than 1µA. The MAX5842 features three software-selec-table power-down output impedances: 100k Ω, 1k Ω,and high impedance. Other features include internal precision Rail-to-Rail ®output buffers and a power-on reset (POR) circuit that powers up the DAC in the 100k Ωpower-down mode.The MAX5842 features a double-buffered I 2C-compati-ble serial interface that allows multiple devices to share a single bus. All logic inputs are CMOS-logic compati-ble and buffered with Schmitt triggers, allowing direct interfacing to optocoupled and transformer-isolated interfaces. The MAX5842 minimizes digital noise feedthrough by disconnecting the clock (SCL) signal from the rest of the device when an address mismatch is detected.The MAX5842 is specified over the extended tempera-ture range of -40°C to +85°C and is available in a miniature 10-pin µMAX package.

The device consists of a serial interface, power-down cir-cuitry, four input and DAC registers, four 12-bit resistor string DACs, four unity-gain output buffers, and output resistor networks. The serial interface decodes the address and control bits, routing the data to the proper input or DAC register. Data can be directly written to the DAC register, immediately updating the device out-put, or can be written to the input register without changing the DAC output. Both registers retain data as long as the device is powered.DAC OperationThe MAX5842 uses a segmented resistor string DAC architecture, which saves power in the overall system and guarantees output monotonicity. The MAX5842’s input coding is straight binary, with the output voltage given by the following equation:where N = 12 (bits), and D = the decimal value of the input code (0 to 4095).Output BufferThe MAX5842 analog outputs are buffered by preci-sion, unity-gain followers that slew 0.5V/µs. Each buffer output swings rail-to-rail, and is capable of driving 5k Ωin parallel with 200pF. The output settles to ±0.5LSB within 4µs.Power-On ResetThe MAX5842 features an internal POR circuit that ini-tializes the device upon power-up. The DAC registersare set to zero scale and the device is powered down,with the output buffers disabled and the outputs pulled to GND through the 100k Ωtermination resistor.Following power-up, a wake-up command must be initi-ated before any conversions are performed.Power-Down ModesThe MAX5842 has three software-controlled, low-power, power-down modes. All three modes disable the output buffers and disconnect the DAC resistor strings from REF, reducing supply current draw to 1µA and the reference current draw to less than 1µA. I n power-down mode 0, the device output is high imped-ance. I n power-down mode 1, the device output is internally pulled to GND by a 1k Ωtermination resistor.I n power-down mode 2, the device output is internally pulled to GND by a 100k Ωtermination resistor. Table 1shows the power-down mode command words.Upon wake-up, the DAC output is restored to its previ-ous value. Data is retained in the input and DAC regis-ters during power-down mode.Digital InterfaceThe MAX5842 features an I 2C/SMBus-compatible 2-wire interface consisting of a serial data line (SDA)and a serial clock line (SCL). The MAX5842 is SMBus compatible within the range of V DD = 2.7V to 3.6V. SDA and SCL facilitate bidirectional communication between the MAX5842 and the master at rates up to 400kHz.Figure 1 shows the 2-wire interface timing diagram. The MAX5842 is a transmit/receive slave-only device, rely-ing upon a master to generate a clock signal. The mas-ter (typically a microcontroller) initiates data transfer on the bus and generates SCL to permit that transfer.A master device communicates to the MAX5842 by transmitting the proper address followed by commandand/or data words. Each transmit sequence is framedMAX5842Quad, 12-Bit, Low-Power, 2-Wire, SerialVoltage-Output DAC_______________________________________________________________________________________9by a START (S) or REPEATED START (S r ) condition and a STOP (P) condition. Each word transmitted over the bus is 8 bits long and is always followed by an acknowledge clock pulse.The MAX5842 SDA and SCL drivers are open-drain outputs, requiring a pullup resistor to generate a logic high voltage (see Typical Operating Circuit). Series resistors R S are optional. These series resistors protect the input stages of the MAX5842 from high-voltage spikes on the bus lines, and minimize crosstalk and undershoot of the bus signals.Bit TransferOne data bit is transferred during each SCL clock cycle. The data on SDA must remain stable during the high period of the SCL clock pulse. Changes in SDA while SCL is high are control signals (see STAR T andSTOP Conditions). Both SDA and SCL idle high when the I 2C bus is not busy.START and STOP ConditionsWhen the serial interface is inactive, SDA and SCL idle high. A master device initiates communication by issu-ing a START condition. A START condition is a high-to-low transition on SDA with SCL high. A STOP condition is a low-to-high transition on SDA, while SCL is high (Figure 2). A START condition from the master signals the beginning of a transmission to the MAX5842. The master terminates transmission by issuing a not acknowledge followed by a STOP condition (see Acknowledge Bit (ACK )). The STOP condition frees the bus. I f a repeated START condition (Sr) is generated instead of a STOP condition, the bus remains active.When a STOP condition or incorrect address is detect-ed, the MAX5842 internally disconnects SCL from the serial interface until the next START condition, minimiz-ing digital noise and feedthrough.Early STOP ConditionsThe MAX5842 recognizes a STOP condition at any point during transmission except if a STOP condition occurs in the same high pulse as a START condition (Figure 3). This condition is not a legal I 2C format; at least one clock pulse must separate any START and STOP conditions.Repeated START ConditionsA REPEATED START (S r ) condition may indicate a change of data direction on the bus. Such a change occurs when a command word is required to initiate a read operation. S r may also be used when the bus master is writing to several I 2C devices and does not want to relinquish control of the bus. The MAX5842 ser-ial interface supports continuous write operations with or without an S r condition separating them. ContinuousM A X 5842Quad, 12-Bit, Low-Power, 2-Wire, Serial Voltage-Output DAC 10read operations require S r conditions because of the change in direction of data flow.Acknowledge Bit (ACK)The acknowledge bit (ACK) is the ninth bit attached to any 8-bit data word. ACK is always generated by the receiving device. The MAX5842 generates an ACK when receiving an address or data by pulling SDA low during the ninth clock period. When transmitting data,the MAX5842 waits for the receiving device to generate an ACK. Monitoring ACK allows for detection of unsuc-cessful data transfers. An unsuccessful data transfer occurs if a receiving device is busy or if a system fault has occurred. I n the event of an unsuccessful data transfer, the bus master should reattempt communica-tion at a later time.Slave AddressA bus master initiates communication with a slave device by issuing a START condition followed by the 7-bit slave address (Figure 4). When idle, the MAX5842waits for a START condition followed by its slaveaddress. The serial interface compares each address value bit by bit, allowing the interface to power down immediately if an incorrect address is detected. The LSB of the address word is the Read/Write (R/W ) bit.R/W indicates whether the master is writing to or read-ing from the MAX5842 (R/W = 0 selects the write condi-tion, R/W = 1 selects the read condition). After receiving the proper address, the MAX5842 issues anACK by pulling SDA low for one clock cycle.The MAX5842 has four different factory/user-pro-grammed addresses (Table 2). Address bits A6through A1 are preset, while A0 is controlled by ADD.Connecting ADD to GND sets A0 = 0. Connecting ADD to V DD sets A0 = 1. This feature allows up to four MAX5842s to share the same bus.Write Data FormatIn write mode (R/W = 0), data that follows the address byte controls the MAX5842 (Figure 5). Bits C3-C0 con-figure the MAX5842 (Table 3). Bits D11-D0 are DAC data. I nput and DAC registers update on the falling edge of SCL during the acknowledge bit. Should the write cycle be prematurely aborted, data is not updated and the write cycle must be repeated. Figure 6 shows two example write data sequences.Extended Command ModeThe MAX5842 features an extended command mode that is accessed by setting C3-C0 = 1 and D11-D8 = 0.The next data byte writes to the shutdown registers (Figure 7). Setting bits A, B, C, or D to 1 sets that DACFigure 2. START and STOP ConditionsFigure 3. Early STOP ConditionsMAX5842Quad, 12-Bit, Low-Power, 2-Wire, SerialVoltage-Output DAC______________________________________________________________________________________11to the selected power-down mode based on the states of PD0 and PD1 (Table 1). Any combination of the four DACs can be controlled with a single write sequence.Read Data FormatIn read mode (R/W = 1), the MAX5842 writes the con-tents of the DAC register to the bus. The direction of data flow reverses following the address acknowledge by the MAX5842. The device transmits the first byte of data, waits for the master to acknowledge, then trans-mits the second byte. Figure 8 shows an example read data sequence.I 2C CompatibilityThe MAX5842 is compatible with existing I 2C systems.SCL and SDA are high-impedance inputs; SDA has an open drain that pulls the data line low during the ninth clock pulse. The Typical Operating Circuit shows a typ-ical I 2C application. The communication protocol sup-ports the standard I 2C 8-bit communications. The general call address is ignored. The MAX5842 address is compatible with the 7-bit I 2C addressing protocol only. No 10-bit address formats are supported.Digital Feedthrough SuppressionWhen the MAX5842 detects an address mismatch, the serial interface disconnects the SCL signal from the core circuitry. This minimizes digital feedthrough caused by the SCL signal on a static output. The serial interface reconnects the SCL signal once a valid START condition is detected.Applications InformationDigital Inputs and Interface LogicThe MAX5842 2-wire digital interface is I 2C/SMBus compatible. The two digital inputs (SCL and SDA) load the digital input serially into the DAC. Schmitt-trigger buffered inputs allow slow-transition interfaces such as optocouplers to interface directly to the device. The digital inputs are compatible with CMOS logic levels.Power-Supply Bypassing andGround ManagementCareful PC board layout is important for optimal system performance. Keep analog and digital signals separate to reduce noise injection and digital feedthrough. Use a ground plane to ensure that the ground return from GND to the power-supply ground is short and low impedance. Bypass V DD with a 0.1µF capacitor to ground as close to the device as possible.Chip InformationTRANSISTOR COUNT: 17,213PROCESS: BiCMOSFigure 6.

Settling Time Test CircuitDetailed DescriptionThe MAX9550/MAX9551/MAX9552 operational transcon-ductance amplifiers (OTA) hold the VCOM voltage sta-ble while providing the ability to source and sink a high current quickly (800mA typ) into a capacitive load such as the backplane of a TFT-LCD panel. The output settles to within 0.1% in less than 2µs. The fast settling time is achieved by increasing the transconductance of the buffer as the output current increases (see the Typical Operating Characteristics ).In addition, the MAX9550/MAX9551/MAX9552 directly drive the capacitive load in the VCOM layer of the TFT LCD without the need for a series resistor.The MAX9550/MAX9551/MAX9552 unity-gain band-width is:GBW = g M / 2πC OUT where C OUT is the capacitive load at the output and g M is the transconductance.To insure buffer stability, place a 1µF low-ESR capaci-tor as close to the OUT pin as possible. However, this value may be reduced if the TFT-LCD panel load pro-vides some of the capacitance and the resistance in series when this capacitance is low. Connect the feed-back at OUT using a Kelvin connection at the low-ESR capacitor.Thermal Shutdown with TemperatureHysteresisThe MAX9550/MAX9551/MAX9552 are capable of high output currents and therefore, feature thermal-shutdown protection with temperature hysteresis. When the die tem-perature reaches +160°C, the devices shut down. When the die cools down by 15°C, the devices turn on again.MAX9550/MAX9551/MAX9552High-Current VCOM Drive Buffersfor TFT LCDs_______________________________________________________________________________________7Applications InformationOutput Load CapacitorThe output load capacitor must have a low ESR value (50m Ωor lower) and it must be placed as close as pos-sible to the OUT pin to ensure buffer stability (see Figure 2). Ceramic capacitors are an excellent choice.Power Supplies and Bypass CapacitorsThe MAX9550/MAX9551/MAX9552 operate from a 6V to 20V single supply, or from ±3V to ±10V dual supplies.Proper supply bypassing ensures stability while driving high transient loads. The MAX9550/MAX9551/MAX9552require minimum 4.7µF (C1)and 0.1µF (C2) power-sup-ply bypass capacitors placed as close as possible tothe power-supply pin (V DD ). See Figure 2.For dual-supply operation, use 4.7µF and 0.1µF bypass capaci-tors on both supplies (V DD and GND) with each capacitor placed as close as possible to the V DD and GND pins.Layout and GroundingThe exposed paddle on the µMAX and TSSOP pack-ages provides a low thermal resistance for heat dissi-pation. Solder the exposed paddle to a ground plane for best results. Do not route traces under these pack-ages. For dual-supply operation, the exposed paddle (EP) must be electrically connected to the negative supply or it can be left unconnected.Figure 2.
