DAC1282IPWR

低失真数位类比转换器用于地震 LOW DISTORTION DIGITAL-TO-ANALOG CONVERTER FOR SEISMIC

DESCRIPON

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.
