Description
General part information
ADS7870 Series
The ADS7870 (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, 12-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.
