Analog Devices AD7837/AD7847 Product Handbook Rev C
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.

Questions answered in these manuals
What is the allowed VDD and VSS voltage range?
VDD may be between 14.25 V and 15.75 V, and VSS may be between –14.25 V and –15.75 V.
How should the power supply pins be decoupled?
Decouple VDD and VSS to DGND with a 10 µF capacitor in parallel with a 0.1 µF ceramic capacitor.
What is the operating temperature range for the commercial/industrial versions?
The commercial/industrial versions operate from –40 °C to +85 °C.
