This document describes the features and characteristics of the 16 V, 4 MHz RR0 amplifiers AD8665/AD8666/AD8668, including offset voltage, input bias current, supply voltage, noise, bandwidth, etc.
The AD866x family are single‑supply, rail‑to‑rail output amplifiers with low noise, low input bias current, and a wide operating voltage range up to 16 V. They are suited for sensor amplification, reference buffers, medical equipment, photodiode amplification, ADC drivers, and level‑shifting circuits.
The document lists detailed electrical specifications, absolute maximum ratings, thermal resistance data, typical performance curves, package dimensions, and an ordering guide that includes automotive‑qualified versions of the AD8666 and AD8668.
