This document describes the features and characteristics of the AD8138 low distortion differential ADC driver, including easy-to-use single-ended-to-differential conversion, adjustable output common-mode voltage, externally adjustable gain, low harmonic distortion, fast settling, low input voltage noise, etc.
The AD8138 provides single‑ended‑to‑differential conversion, adjustable output common‑mode voltage, and externally adjustable gain. It is designed for high‑bandwidth, low‑noise applications such as ADC drivers, IF and baseband gain blocks, and differential buffers.
The device is offered in 8‑lead SOIC and MSOP packages, operates from +3 V to ±5 V, and supports temperatures from –40 °C to +85 °C. Detailed layout, grounding, and bypassing recommendations are included to preserve its high‑speed performance.
