Product Details

Quad/octal 10-bit digital-to-analog converters with serial load capabilities are the AD7804/AD7808, while parallel load capabilities are provided by the AD7805/AD7809. With an on-chip reference, these components run off a +3.3 V to +5 V power supply. These DACs produce signals known as VBIAS as their output. Internally, VBIAS is used to create VSWING. There are two types of on-chip control registers: channel control registers and system control registers. All of the DACs in the package are controlled by the system control register. Individual DAC control is possible thanks to the channel control registers. Using an on-chip Sub DAC, the whole transfer function of each individual DAC may be moved around the VBIAS point. Double buffered data inputs are present in all DACs, enabling simultaneous updating of all analogue outputs.
