AD8802ARZ

AD8802 is a 12 channel, 8bit TrimDAC with power shutdown. This potentiometer divider TrimDAC® allows replacement of the mechanical trimmer function in new designs. It is ideal for dc voltage adjustment applications. Easily programmed by serial interfaced microcontroller ports, this device 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. Each DAC has its own DAC latch that holds its output state. It is used in application such as automatic adjustment, trimmer replacement, video and audio equipment gain and offset adjustment, portable and battery operated equipment etc.
