This data sheet provides the static performance, reference inputs, digital inputs, analog outputs and power requirements specifications for the AD7837/AD7847.
This handbook details the electrical specifications, absolute maximum ratings, and ordering options for the AD7837 and AD7847 dual 12‑bit digital‑to‑analog converters. It includes pin‑out tables, timing diagrams, and typical performance graphs covering gain, bandwidth, noise, and distortion.
Application sections describe how to use the devices as programmable gain amplifiers, in bipolar and unipolar configurations, and provide guidance on ground management, power‑supply decoupling, and interfacing to common microprocessors.

VDD may be between 14.25 V and 15.75 V, and VSS may be between –14.25 V and –15.75 V.
Decouple VDD and VSS to DGND with a 10 µF capacitor in parallel with a 0.1 µF ceramic capacitor.
The device can tolerate VDD to DGND from –0.3 V up to +17 V.
