概述
Description
AD8801AR is an 8‑bit multiplying digital‑to‑analog converter (MDAC) from Analog Devices. It accepts an 8‑bit digital input and uses an external reference to set full‑scale, producing an output current proportional to the input and reference. The AR suffix denotes a commercial‑grade version in a standard package. The device is typically used for programmable gain/attenuation, calibration, and precision control loops. Because it provides a current output, you usually use an external op‑amp (I/V stage) to convert Iout to a voltage. It’s suitable for fast, low‑noise applications and integrates well in instrumentation, data acquisition, and waveform generation circuits. For exact pinout, interface (parallel/serial), reference requirements, and electrical specs, consult the AD8801AR datasheet.
Pinout
- Pin count: 8 pins (DIP-8/SOIC-8 in the AR package).
- Function: 8‑bit multiplying digital‑to‑analog converter (MDAC). It converts an 8‑bit digital word to an analog current (Iout) which is typically converted to a voltage with an external op-amp; requires external reference/power connections.
