16-bit 400KSPS 4-Ch. Multiplexed Data Acquisition Ref Design for High Voltage Inputs: Low Distortion
Description
This TI Verified Design implements a 16-bit: differential 4-channel multiplexed data acquisition system at 400KSPS throughput for high voltage differential input of ±20 V (40 Vpk-pk) industrial applications. The circuit is realized with a 16-bit successive-approximation-resistor (SAR) analog-to-digital converter (ADC): a precision high voltage signal conditioning front end: and a 4-channel differential multiplexer (MUX). The design details the process for optimizing the precision high voltage front end drive circuit using the OPA192 and OPA140 to achieve excellent dynamic performance with the ADS8864.
