DAC8568 - Texas Instruments

DAC8568 D/A Converter

The DAC7568, DAC8168, and DAC8568 are lowpower, voltage-output, eight-channel, 12-, 14-, and 16-bit digital-to-analog converters (DACs), respectively. These devices include a 2.5V, 2ppm/°C internal reference (disabled by default), giving a fullscale output voltage range of 2.5V or 5V. The internal reference has an initial accuracy of 0.004% and can source up.
