Product Summary

The AD8821ARZ/AD8221ARMZ is an Octal 8-Bit TrimDAC with Power Shutdown, which 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.
