DAC1282IPWR Datasheet PDF - TI

●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.
