This Verified Precision Design details the design procedure, simulated results, and showcases the actual performance of a 12-bit discrete data acquisition block using the ADS7042, optimized for extremely low power, small form factor applications for the following three different optimizations:
Optimization #1: 12 bit, 500ksps optimized for current monitoring, battery monitoring, electromyography (EMG), skin impedance, and wearable fitness
Optimization #2: 12 bit, 1Msps optimized for hard disc drives, motor control, motor encoders, optical encoders, and optical modules
Optimization #3: 12 bit, < 1ksps optimized for tilt, gyro, pressure, temperature, gas, chemical, blood glucose, low voltage (1.8V-3.3V, JESD8-7A), and DC sensor measurements

The ADS7042EVM-PDK is a platform for evaluation of the ADS7042 analog to Digital converter (ADC). The converter is an 12 bit single-ended Successive Approximation-Register (SAR) ADC with a maximum throughput of 1MSPS. The evaluation kit combines the ADS7042EVM board with a serial data capture card (...)
