Description

General part information

DAC1282 Series

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.

The DAC1282 integrates a digital signal generator, a DAC, and an output amplifier providing sine wave, dc, and pulse output voltages.

The output frequency is programmable from 0.5 Hz to 250 Hz and the magnitude is scaled by both analog and digital control. The analog gain is adjustable in 6-dB steps and the digital gain in 0.5-dB steps. The analog gain settings match those of the ADS1282 for testing at all gains with high resolution.
