Product Summary

The ADS7871IDB is a complete low power data acquisition system on a single chip. The ADS7871IDB consists of a 4-channel differential/8-channel single-ended multiplexer, precision programmable gain amplifier, 14-bit successive approximation analog-todigital (A/D) converter, and a precision voltage reference. The programmable-gain amplifier provides high input impedance, excellent gain accuracy, good common-mode rejection, and low noise. The applications of the ADS7871IDB include Portable Battery-Powered Systems, Low-Power Instrumentation, Low-Power Control Systems and Smart Sensor Applications.
