AD8801 - Octal 8-Bit TrimDAC with Power Shutdown

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.

Features

  • Low Cost Replaces Eight Potentiometers Eight Individually Programmable Outputs Three-Wire Serial Input Power Shutdown ≤ 25 ␮W Including IDD and IREF Midscale Preset, AD8801 Separate V REFL Range Setting, AD8803 +3 V to +5 V Single Supply Operation.
