3 Description
The ADS1282-HT device is an extremely highperformance,
single-chip analog-to-digital converter
(ADC) with an integrated, low-noise programmable
gain amplifier (PGA) and two-channel input
multiplexer (MUX). The ADS1282-HT device is
suitable for the demanding needs of energy
exploration and seismic monitoring environments.
