This document introduces the features and characteristics of the AD8691/AD8692/AD8694 three low-cost, low-noise, CMOS, RRO operational amplifiers.
The AD8691, AD8692, and AD8694 are low‑cost, single‑, dual‑, and quad‑channel rail‑to‑rail output, single‑supply operational amplifiers. They combine ultra‑low offset voltage, low input bias current, low noise, and a wide 10 MHz bandwidth, making them suitable for photodiode amplification, battery‑powered instrumentation, medical devices, sensors, and portable audio.
These amplifiers are offered in SC70, TSOT, MSOP, SOIC, and TSSOP packages and operate over an extended industrial temperature range of –40 °C to +125 °C. They support single‑supply operation from 2.7 V to 6 V and are qualified for automotive applications.
