Data Sheet 100637D © 2001, 2002 Skyworks Solutions, Inc., All Rights Reserved.March 22, 2002RM914Power Amplifier Module for AMPS Applications (824–849 MHz)The RM914 Advanced Mobile Phone Service (AMPS) Power Amplifier is a fully matched 6-pin surface mount module designed for mobile units operating in the 824-849 MHz cellular bandwidth. This device can be driven to power output levels beyond 31 dBm for high efficiency FM mode operation. A single GaAs Microwave Monolithic Integrated Circuit (MMIC) contains all active circuitry in the module. The MMIC contains on-board bias circuitry as well as input and interstage matching circuits. The output match is realized off-chip and within the module package to optimize efficiency and power performance into a 50 Ω load. This device is manufactured with Skyworks’s GaAs HBT process that provides for all positive voltage DC supply operation while maintaining high efficiency. Primary bias to the RM914 can be supplied directly from a three cell nickel-cadmium, single celllithium-ion, or other suitable battery with output in the 3-4 volt range. Power down is accomplished by setting the voltage on the low current reference pin to zero volts. No external supply side switch is needed as typical “off” leakage is a few microamperes with full primary voltage supplied from the battery.Functional Block DiagramDistinguishing Features•Low voltage positive bias supply (3 to 4 Volts, typical)•High efficiency•Large dynamic range •6-pin package(6mm x 6mm x 1.5 mm)•Power down controlApplications•Analog cellular (AMPS)•Wireless local loop (WLL)Electrical SpecificationsRM914Power Amplifier Module for AMPS Applications (824–849 MHz)2Skyworks100637DMarch 22, 2002Electrical SpecificationsThe following tables list the electrical characteristics of the RM914 Power Amplifier.

Figure 14 lists the Electrostatic Discharge (ESD) immunity level for each pin of the RM914 product. The numbers in Figure 14 specify the ESD threshold level for each pin where the I-V curve between the pin and ground starts to show degradation. The ESD testing was performed in compliance with MIL-STD-883E Method 3015.7 using the Human Body Model. Since 2000 volts represents the maximum measurement limit of the test equipment used, pins marked > 2000 V pass 2000V ESD stress.Various failure criteria can be utilized when performing ESD testing. Many vendors employ relaxed ESD failure standards which fail devices only after “the pin fails the electrical specification limits” or “the pin becomes completely non-functional”. Skyworks employs the most stringent criteria and fails devices as soon as the pin begins to show any degradation on a curve tracer.To avoid ESD damage, latent or visible, it is very important the Class-1 ESD handling precautions listed in Table 6 be used in the product assembly and test areas follow.Figure 14.ESD Sensitivity AreasTable 6.Precautions for GaAs ICs with ESD Thresholds Greater Than 200V But Less Than 2000VPersonnel GroundingWrist StrapsConductive Smocks, Gloves and Finger Cots Antistatic ID BadgesFacilityRelative Humidity Control and Air Ionizers Dissipative Floors (less than 109 Ω to GND)Protective WorkstationDissipative Table TopsProtective Test Equipment (Properly Grounded)Grounded Tip Soldering Irons Conductive Solder Suckers Static SensorsProtective Packaging & TransportationBags and Pouches (Faraday Shield)Protective Tote Boxes (Conductive Static Shielding)Protective Trays Grounded CartsProtective Work Order Holders© 2002, Skyworks Solutions, Inc.

10-位 PWM 输出模式是连续输出所测物体温度的标准配置，测量物体的温度范围为-20…120 °C，分辨 率为 0.14 °C。PWM 通过修改 EEPROM 内 2 个单元的值，实际上可以根据需求调整至任何温度范围，而这对 出厂校准结果并无影响。
传感器的测量结果均出厂校准化，数据接口为数字式的 PWM 和 SMBus(System Management Bus) 输出。
作为标准，PWM 为 10 位，且配置为-20˚C 至 120 ˚C 内，分辨率为 0.14 ˚C 的连续输出。
传感器出厂默认，上电复位时为 SMBus 通信。

PWM 引脚也可配置为热继电器(输入是 To)，这样可以实现简单且性价比高的恒温控制器或温度报警(冰 点/沸点)应用，其中的温度临界值是用户可编程的。在 SMBus 系统里，这个功能可以作为处理器的中断信号， 以此触发读取主线上从动器的值，并确定精度条件。
传感器有两种供电电压选择：5V 或 3V(电池供电)。其中，5V 也可简便的从更高供电电压(例如 8 至 16V)上通过外接元件调制。(具体请参考“应用信息”)

General DescriptionThe MAX9140/MAX9141 are single and the MAX9142/MAX9144 are dual/quad high-speed comparators optimized for systems powered from a 3V or 5V supply. The MAX9141 features latch enable and device shutdown. These devices combine high speed, low power, and rail-to-rail inputs. Propagation delay is 40ns, while supply current is only 150μA per comparator.The input common-mode range of the devices extends beyond both power-supply rails. The outputs pull to within 0.3V of either supply rail without external pullup circuitry, making these devices ideal for interface with both CMOS and TTL logic. All input and output pins can tolerate a continuous short-circuit fault condition to either rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals.The devices are higher-speed, lower-power, and lower-cost upgrades to industry-standard comparators MAX941/MAX942/MAX944.The MAX9140 are offered in tiny 5-pin SC70 and SOT23 packages. The MAX9141 and MAX9142 are available in 8-pin SOT23 and SO packages, while the MAX9144 is available in both 14-pin SO and TSSOP packages.Applications●Line Receivers●Battery-Powered Systems●Threshold Detectors/Discriminators ●3V/5V Systems●Zero-Crossing Detectors●Sampling CircuitsFeatures●Fast, 40ns Propagation Delay (10mV Overdrive) ●Low Power• 150μA Supply Current Per Comparator (3V) ●Optimized for 3V and 5V Applications ●Rail-to-Rail Input Voltage Range ●Low, 500μV Offset Voltage●Internal Hysteresis for Clean Switching ●Outputs Swing 300mV of Power Rails ●CMOS/TTL-Compatible Outputs ●Output Latch (MAX9141 Only)●Shutdown Function (MAX9141 Only) ●Available in SC70 and SOT23 Packages●AEC-Q100 Qualified (MAX9140AAXK/V+T Only)19-2064; Rev 9; 10/19Click here for production status of specific part numbers.MAX9140/MAX9141/MAX9142/MAX914440ns, Low-Power, 3V/5V, Rail-to-RailSingle-Supply ComparatorsPin ConfigurationsPower-Supply RangesSupply Voltage (V CC to GND) ...........................................+6V IN+, IN- to GND ....................................-0.3V to (V CC + 0.3V) LE Input Voltage (MAX9141 only) ........-0.3V to (V CC + 0.3V) SHDN Input Voltage (MAX9141 only) ..-0.3V to (V CC + 0.3V)Current into Input Pins .....................................................±20mA Input/Output Short-Circuit Duration toV CC or GND ..........................................................Continuous Continuous Power Dissipation (T A = +70°C)5-Pin SC70 (derate 3.1mW/°C above +70°C) .............247mW 5-Pin SOT23 (derate 7.1mW/°C above +70°C) ..........571mW8-Pin SOT23 (derate 9.1mW/°C above +70°C) ..........727mW 8-Pin SO (derate 5.9mW/°C above +70°C) ..............470.6mW 14-Pin TSSOP (derate 9.1mW/°C above +70°C) ........727mW 14-Pin SO (derate 8.33mW/°C above +70°C) ..........666.7mW Operating Temperature RangeE grade ...........................................................-40°C to +85°C A grade .........................................................-40°C to +125°C Junction Temperature ......................................................+150°C Storage Temperature Range ............................-65°C to +150°C Lead Temperature (soldering, 10s) .................................+300°C(V CC = 5V, V CM = 0V, SHDN = LE = V CC (MAX9141 only), C L = 15pF, T A = T MIN to T MAX , unless otherwise noted.

Their outputs are pulled to within 300mV of either supply rail without external pullup or pulldown circuitry. Rail-to-rail input voltage range and low-voltage single-supply operation make these devices ideal for portable equipment. The devices interface directly to CMOS and TTL logic.Most high-speed comparators oscillate in the linear region because of noise or undesired parasitic feedback. This tends to occur when the voltage on one input is at or equal to the voltage on the other input. To counter the parasitic effects and noise, the devices have an internal hysteresis of 1.5mV.The hysteresis in a comparator creates two trip points: one for the rising input voltage and one for the falling input voltage (Figure 1). The difference between the trip points is the hysteresis. The average of the trip points is the offset voltage. When the comparator’s input voltages are equal, the hysteresis effectively causes one comparator input voltage to move quickly past the other, thus taking theinput out of the region where oscillation occurs. Standard comparators require hysteresis to be added with external resistors. The devices’ fixed internal hysteresis eliminates these resistors. To increase hysteresis and noise margin even more, add positive feedback with two resistors as a voltage divider from the output to the noninverting input. Figure 1 illustrates the case where IN- is fixed and IN+ is varied. If the inputs were reversed, the figure would look the same, except the output would be inverted.The MAX9141 includes an internal latch that allows storage of comparison results. The LE pin has a high input impedance. If LE is high, the latch is transparent (i.e., the comparator operates as though the latch is not present). The comparator’s output state is latched when LE is pulled low (Figure 2).Shutdown Mode (MAX9141 Only)The MAX9141 shuts down when the SHDN pin is low. When shut down, the supply current drops to less than 12μA, and the three-state output becomes high impedance. The SHDN pin has a high-input impedance. Connect SHDN to V CC for normal operation. Exit shutdown with LE high (transparent state); otherwise, the output will be indeterminate.Input Stage CircuitryThe devices include internal protection circuitry that prevents damage to the precision input stage from large differential input voltages. This protection circuitry consists of two back-toback diodes between IN+ and IN- as well as two series 4.1kΩ resistors (Figure 3). The diodes limit the differential voltage applied to the internal circuitry of the comparators to be no more than 2V F, where V F is the forward voltage drop of the diode (about 0.7V at +25°C). For a large differential input voltage (exceeding 2V F), this protection circuitry increases the input bias current at IN+ (source) and IN- (sink).F(IN+ - IN-) - 2VInput Current2 4.1k=×ΩInput current with large differential input voltages should not be confused with input bias current (I B). As long as the differential input voltage is less than 2V F, this input current is equal to I B. The output is in the correct logic state if one or both inputs are within the common-mode range. Figure 1. Input and Output Waveform, Noninverting Input VariedMAX9142/MAX9144Single-Supply ComparatorsOutput Stage CircuitryThe MAX9140/MAX9141/MAX9142/MAX9144 contain a current-driven output stage as shown in Figure 4. During an output transition, I SOURCE or I SINK is pushed or pulled to the output pin. The output source or sink current is high during the transition, creating a rapid slew rate. Once the output voltage reaches V OH or V OL , the source or sink current decreases to a small value, capable of maintaining the V OH or V OL static condition. This significant decrease in current conserves power after an output transition has occurred.One consequence of a current-driven output stage is a linear dependence between the slew rate and the load capacitance. A heavy capacitive load will slow down a voltage output transition. This can be useful in noisesensitive applications where fast edges may cause interference.Applications InformationCircuit Layout and BypassingThe high-gain bandwidth of the MAX9140/MAX9141/MAX9142/MAX9144 requires design precautions to real-ize the full high-speed capabilities of these comparators. The recommended precautions are:1) Use a PCB with a good, unbroken, low-inductance ground plane.2) Place a decoupling capacitor (a 0.1μF ceramic capacitor is a good choice) as close to V CC as possible.3) Pay close attention to the decoupling capacitor’s bandwidth, keeping leads short.4) On the inputs and outputs, keep lead lengths short to avoid unwanted parasitic feedback around the comparators.5) Solder the device directly to the PCB instead of using a socket.Figure 2.
