SBAS490B – DECEMBER 2011 – REVISED MAY 2015 DAC1282 Low Distortion Digital-to-Analog Converter for Seismic
1 Features 3 Description The DAC1282 is a fully-integrated digital-to-analog
converter (DAC) providing low distortion, digital
synthesized voltage output suitable for testing of
seismic equipment. The DAC1282 achieves very high
performance in a small package with low power.
Together, with the high-performance ADS1281 and
ADS1282 analog-to-digital converters (ADCs), these
devices create a measurement system that meets the
exacting demands of seismic data acquisition
equipment. 1 Single-Chip Test Signal Generator
