Analog Devices ADA4938-1/ADA4938-2 Handbook

About this manual

The ADA4938‑1 (single amplifier) and ADA4938‑2 (dual amplifier) are ultralow distortion, high‑speed differential ADC drivers with adjustable gain and common‑mode voltage. They are designed for driving high‑performance ADCs up to 16‑bit resolution and feature extremely low harmonic distortion and low input voltage noise.

The handbook includes detailed specifications for both dual‑supply and single‑supply operation, absolute maximum ratings, thermal resistance data, pin‑out diagrams, and application notes such as layout, grounding, and high‑performance ADC driving techniques.
