Evaluation Board for ISL8225M Dual 15 A Single 30 A Step-Down Power Module

The HMC7912 is a compact, gallium arsenide (GaAs), pseudomorphic(pHEMT), monolithic microwave integrated circuit(MMIC) upconverter in a RoHS compliant, low stress, injectionmolded plastic LFCSP package that operates from 21 GHz to24 GHz. This device provides a small signal conversion gain of15 dB with 22 dBc of sideband rejection. The HMC7912 uses avariable gain amplifier preceded by an in-phase/quadrature (I/Q)mixer that is driven by an active 2? LO multiplier. IF1 and IF2mixer inputs are provided, and an external 90? hybrid is needed toselect the required sideband. The I/Q mixer topology reducesthe need for filtering of the unwanted sideband. The HMC7912is a much smaller alternative to hybrid style single sideband (SSB)upconverter assemblies, and it eliminates the need for wirebonding by allowing the use of surface-mount manufacturingtechniques.Applications Point to point and point to multipoint radios Military radars, electronic warfare (EW), and electronic intelligence (ELINT) Satellite communications Sensors

The ADXL362 is an ultralow power, 3-axis MEMS accelerometer that consumes less than 2 ?A at a 100 Hz output data rate and 270 nA when in motion triggered wake-up mode. Unlike accelerometers that use power duty cycling to achieve low power consumption, the ADXL362 does not alias input signals by undersampling; it samples the full bandwidth of the sensor at all data rates.The ADXL362 always provides 12-bit output resolution; 8-bit formatted data is also provided for more efficient single-byte transfers when a lower resolution is sufficient. Measurement ranges of ?2 g, ?4 g, and ?8 g are available, with a resolution of 1 mg/LSB on the ?2 g range. For applications where a noise level lower than the normal 550 ?g/?Hz of the ADXL362 is desired, either of two lower noise modes (down to 175 ?g/?Hz typical) can be selected at minimal increase in supply current.In addition to its ultralow power consumption, the ADXL362 has many features to enable true system level power reduction. It includes a deep multimode output FIFO, a built-in micropower temperature sensor, and several activity detection modes including adjustable threshold sleep and wake-up operation that can run as low as 270 nA at a 6 Hz (approximate) measurement rate. A pin output is provided to directly control an external switch when activity is detected, if desired. In addition, the ADXL362 has provisions for external control of sampling time and/or an external clock.The ADXL362 operates on a wide 1.6 V to 3.5 V supply range, and can interface, if necessary, to a host operating on a separate, lower supply voltage. The ADXL362 is available in a 3 mm ? 3.25 mm ? 1.06 mm package.APPLICATIONS Hearing aids Home healthcare devices Motion enabled power save switches Wireless sensors Motion enabled metering devices

The AD5940 and AD5941 are high precision, low power analog front ends (AFEs) designed for portable applications that require high precision, electrochemical-based measurement techniques, such as amperometric, voltammetric, or impedance measurements. The AD5940/AD5941 is designed for skin impedance and body impedance measurements, and works with the AD8233 AFE in a complete bioelectric or biopotential measurement system. The AD5940/AD5941 is designed for electrochemical toxic gas sensing.The AD5940/AD5941 consist of two high precision excitation loops and one common measurement channel, which enables a wide capability of measurements of the sensor under test. The first excitation loop consists of an ultra low power, dual-output string, digital-to-analog converter (DAC), and a low power, low noise potentiostat. One output of the DAC controls the noninverting input of the potentiostat, and the other output controls the noninverting input of the transimpedance amplifier (TIA). This low power excitation loop is capable of generating signals from dc to 200 Hz.The second excitation loop consists of a 12-bit DAC, referred to as the high speed DAC. This DAC is capable of generating high frequency excitation signals up to 200 kHz.The AD5940/AD5941 measurement channel features a 16-bit, 800 kSPS, multichannel successive approximation register (SAR) analog-to-digital converter (ADC) with input buffers, a built in antialias filter, and a programmable gain amplifier (PGA). An input multiplexer (mux) in front of the ADC allows the user to select an input channel for measurement. These input channels include multiple external current inputs, external voltage inputs, and internal channels. The internal channels allow diagnostic measurements of the internal supply voltages, die temperature, and reference voltages.The current inputs include two TIAs with programmable gain and load resistors for measuring different sensor types. The first TIA, referred to as the low power TIA, measures low bandwidth signals. The second TIA, referred to as the high speed TIA, measures high bandwidth signals up to 200 kHz.An ultra low leakage, programmable switch matrix connects the sensor to the internal analog excitation and measurement blocks. This matrix provides an interface for connecting external transimpedance amplifier resistors (RTIAs) and calibration resistors. The matrix can also be used to multiplex multiple electronic measurement devices to the same wearable electrodes.A precision 1.82 V and 2.5 V on-chip reference source is available. The internal ADC and DAC circuits use this on-chip reference source to ensure low drift performance for the 1.82 V and 2.5 V peripherals.The AD5940/AD5941 measurement blocks can be controlled via direct register writes through the serial peripheral interface (SPI) interface, or, alternatively, by using a preprogrammable sequencer, which provides autonomous control of the AFE chip. 6 kB of static random access memory (SRAM) is partitioned for a deep data first in, first out (FIFO) and command FIFO. Measurement commands are stored in the command FIFO and measurement results are stored in the data FIFO. A number of FIFO related interrupts are available to indicate when the FIFO is full.A number of general-purpose inputs/outputs (GPIOs) are available and controlled using the AFE sequencer. The AFE sequencer allows cycle accurate control of multiple external sensor devices.The AD5940/AD5941 operate from a 2.8 V to 3.6 V supply and are specified over a temperature range of ?40?C to +85?C. The AD5940 is packaged in a 56-lead, 3.6 mm ? 4.2 mm WLCSP. The AD5941 is packaged in a 48-lead LFCSP.APPLICATIONS Electrochemical measurements Electrochemical gas sensors Potentiostat/amperometric/voltammetry/cyclic voltammetry Bioimpedance applications Skin impedance Body impedance Continuous glucose monitoring Battery impedance
