Description

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

The converter uses a fourth-order, inherently stable, delta-sigma () modulator that provides outstanding noise and linearity performance. The modulator is used either in conjunction with the on-chip digital filter, or can be bypassed for use with post processing filters.

The flexible input MUX provides an additional external input for measurement, as well as internal self-test connections. The PGA features outstanding low noise (5nV/Hz) and high input impedance, allowing easy interfacing to geophones and hydrophones over a wide range of gains.

The digital filter provides selectable data rates from 250 to 4000 samples per second (SPS). The high-pass filter (HPF) features an adjustable corner frequency. On-chip gain and offset scaling registers support system calibration.

The synchronization input (SYNC) can be used to synchronize the conversions of multiple ADS1282s. The SYNC input also accepts a clock input for continuous alignment of conversions from an external source.

Two operating modes allow optimization of noise and power. Together, the amplifier, modulator, and filter dissipate 25mW and only 17mW in low-power mode. The ADS1282 is available in a compact TSSOP-28 package and is fully specified from –40°C to +85°C, with a maximum operating range to +125°C.
