PRODUCTION DATA.
Figure 33 shows a 16-bit, differential, 4-channel, multiplexed, data-acquisition system. This example is typical in industrial applications that require low distortion and a high-voltage input. The circuit uses the ADS8864, a 16-bit, 400-kSPS successive-approximation-resistor (SAR) analog-to-digital converter (ADC), along with a precision, high-voltage, signal-conditioning front end, and a 4-channel single-ended mux. This TI Precision Design details the process for optimizing the precision, high-voltage, front-end drive circuit using the TMUX6104 and OPA192 to achieve excellent dynamic performance and linearity with the ADS8864.
