Description

DAC 12 CH 8BIT DIP-20

The 12-channel AD8802/AD8804 provides independent digitally- controllable voltage outputs in a compact 20-lead package. This potentiometer divider TrimDAC® allows replacement of the mechanical trimmer function in new designs. The AD8802/ AD8804 is ideal for dc voltage adjustment applications. Easily programmed by serial interfaced microcontroller ports, the AD8802 with its midscale preset is ideal for potentiometer replacement where adjustments start at a nominal value. Appli- cations such as gain control of video amplifiers, voltage con- trolled frequencies and bandwidths in video equipment, geometric correction and automatic adjustment in CRT com- puter graphic displays are a few of the many applications ideally suited for these parts. The AD8804 provides independent con- trol of both the top and bottom end of the potentiometer divider allowing a separate zero-scale voltage setting determined by the VREFL pin. This is helpful for maximizing the resolution of devices with a limited allowable voltage control range. Internally the AD8802/AD8804 contains 12 voltage-output digital-to-analog converters, sharing a common reference- voltage input. TrimDAC is a registered trademark of Analog Devices, Inc.
