Beschreibung

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

Eigenschaften

• Covers three different detailed implementations optimized for speed/power/performance
• Contains Theory, Component Selection, Simulation, Schematic, PCB Layout, and Measured Performance Results for all three implementations
