DAC80508 Datasheet

DAC80508 Voltage-Output DAC

The DACx0508 is a pin-compatible family of low power, eight-channel, buffered voltage-output, digitalto-analog converters (DACs) with 16-, 14- and 12-bit resolution. The DACx0508 includes a 2.5-V, 5ppm/°C internal reference, eliminating the need for an external precision reference in most applicatio.
