AD8803ARZ Datasheet PDF - ADI

●The AD8803ARZ is an octal 8-bit Digital-to-analog Converter (DAC) with power shutdown. It provides eight digitally controlled DC voltage outputs. This potentiometer divider TrimDAC® allows replacement of the mechanical trimmer function in new designs. The AD8803 provides independent control of both the top and bottom end of the potentiometer divider allowing a separate zero-scale voltage setting determined by the VREFL pin. This helpful for maximizing the resolution of devices with a limited allowable voltage control range. This DAC registers are updated from an internal serial-to-parallel shift register that is loaded from a standard 3-wire serial input digital interface. Eleven data bits make up the data word clocked into the serial input register. This data word is decoded where the first 3-bit determine the address of the DAC register to be loaded with the last 8-bit of data. The AD8803 consumes only 5µA from 5V power supplies.
