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.
