Description

The ADS7871 (US patents 6140872, 6060874) is a complete low power data acquisition system on a single chip. It consists of a 4-channel differential/8-channel single-ended multiplexer, precision programmable gain amplifier, 14-bit successive approximation analog-to-digital (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.

For many low-level signals, no external amplification or impedance buffering is needed between the signal source and the A/D input.

The offset voltage of the PGA is auto zeroed. Gains of 1, 2, 4, 5, 8, 10, 16, and 20 V/V allow signals as low as 125 mV to produce full-scale digital outputs.
