VREFH DAC 8 VOUT VREFL 8 O8 GENERAL DESCRIPTION The AD8801/AD8803 provides eight digitally controlled dc voltage outputs. This potentiometer divider TrimDAC allows replacement of the mechanical trimmer function in new designs. The AD8801/AD8803 is ideal for dc voltage adjustment applications. Easily programmed by serial interfaced microcontroller ports, the AD8801 with its midscale preset is ideal for potentiometer replacement where adjustments start at a nominal value. Applications such as gain control of video amplifiers, voltage controlled frequencies and bandwidths in video equipment, geometric correction and automatic adjustment in CRT computer graphic displays are a few of the many applications ideally suited for these parts. The AD8803 provides independent cont……
