Product Overview

The ADS1281IPW is an ultra high resolution delta sigma Analog-to-digital (A/D) Converter for seismic and energy exploration. The ADS1281 is designed for the demanding needs of energy exploration and seismic monitoring environments. The single-chip design promotes board area savings for improvements in high-density applications. 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 digital filter consists of sinc and finite impulse response (FIR) low-pass stages followed by an infinite impulse response (IIR) high-pass filter (HPF) stage. The FIR low-pass stage provides both linear and minimum phase response. The HPF features an adjustable corner frequency. On-chip gain and offset scaling registers support system calibration.
