The AD8801 and AD8803 are octal 8‑bit TrimDACs that replace up to eight mechanical potentiometers. They feature three‑wire serial input, low power consumption (≤ 25 mW), and a shutdown mode that reduces current to a few microamps. The devices are offered in 16‑pin DIP and SO‑16 surface‑mount packages and support both +3 V and +5 V supplies.
The document provides functional block diagrams, detailed pin descriptions, absolute maximum ratings, programming equations, and recommended supply‑bypass techniques. It also includes example interfacing circuits for microcontrollers and external buffers, as well as performance graphs for linearity, settling time, and temperature effects.
