Analog Devices AD7805
The AD7804/AD7808 are quad/octal 10-bit digital-to-analog converters, with serial load capabilities, while the AD7805/AD7809 are quad/octal 10-bit digital-to-analog converters with parallel load capabilities. These parts operate from a +3.3 V to +5 V (± 10%) power supply and incorporates an on-chip reference. These DACs provide output signals in the form of VBIAS ± VSWING.FEATURES
