適用於高電壓輸入、低失真的 16 位元 400 KSPS 四通道多工資料採集參考設計
TIPD151
概覽
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.
