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/В°C
internal reference (disabled by default), giving a fullscale output voltage range of 2.5V or 5V. The internal …
