DAC1280 说明

The DAC1280 is a very low distortion digital-to-analog converter (DAC) that generates a high-accuracy signal from an external bitstream input. The device is optimized for output signal frequencies from dc to 250Hz. The DAC1280 achieves very high linearity 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 energy exploration and seismic monitoring equipment.

The DAC1280 provides a differential current output intended to be used with an external operational amplifier I-to-V converter. The DAC1280 input is driven by an external 1s density digital bitstream.
