Demonstration circuit 1428A features the dual output LT3645 step-down regulator plus linear regulator. The circuit is designed to convert a 5V to 36V (55V transients) input source to 3.3V at 500mA using the buck regulator and this output is linear regulated down to provide 2.5V at 200mA. Thus the two outputs provide 300mA (buck) and 200mA (LDO).

The AD9228 is a quad, 12-bit, 40/65 MSPS analog-to-digital converter (ADC) with an on-chip sample-and-hold circuit designed for low cost, low power, small size, and ease of use. The product operates at a conversion rate of up to 65 MSPS and is optimized for outstanding dynamic performance and low power in applications where a small package size is critical.

PMP841 is a high efficiency, non-isolated Power-over-Ethernet PD power supply reference design intended to ease implementation of PoE in devices such as IP phones, WLAN AP's and security cameras. The reference design uses a TPS2375 PoE Powered Device Controller to implement all necessary detection,

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

The ADL5902 is a true rms responding power detector that hasa 65 dB measurement range when driven with a single-ended 50 ? source. This feature makes the ADL5902 frequencyversatile by eliminating the need for a balun or any other form of external input tuning for operation up to 9 GHz.The ADL5902 provides a solution in a variety of high frequencysystems requiring an accurate measurement of signal power. Requiring only a single supply of 5 V and a few capacitors, it is easy to use and capable of being driven single-ended or with abalun for differential input drive. The ADL5902 can operate from 50 MHz to 9 GHz and can accept inputs from ?62 dBm to at least +3 dBm with large crest factors, such as GSM, CDMA,W-CDMA, TD-SCDMA, WiMAX, and LTE modulated signals.The ADL5902 can determine the true power of a high frequency signal having a complex low frequency modulation envelope or can be used as a simple low frequency rmsvoltmeter. Used as a power measurement device, VOUT isconnected to VSET. The output is then proportional to thelogarithm of the rms value of the input. In other words, thereading is presented directly in decibels and is scaled 1.06 V per decade, or 53 mV/dB; other slopes are easily arranged. In controller mode, the voltage applied to VSET determines thepower level required at the input to null the deviation from the set point. The output buffer can provide high load currents.The ADL5902 has 1.5 mW power consumption when powereddown by a logic high applied to the PWDN pin. It powers up within approximately 5 ?s to its nominal operating current of 73 mA at 25?C. The ADL5902 is supplied in a 4 mm ? 4 mm,16-lead LFCSP for operation over the wide temperature rangeof ?40?C to +125?C.The ADL5902 is also pin-compatible with the AD8363, 50 dBdynamic range TruPwr? detector. This feature allows the designer to create one circuit layout for projects requiring different dynamic ranges. A fully populated RoHS-compliant evaluation board is available.Applications Power amplifier linearization/control loops Transmitter power controls Transmitter signal strength indication (TSSI) RF instrumentation
