The AD8614/AD8644 are single-supply, 5.5 MHz bandwidth, rail-to-rail operational amplifiers optimized for LCD monitor applications.
The AD8614 (single) and AD8644 (quad) are optimized for LCD monitor applications, offering rail‑to‑rail inputs and outputs, low supply current (800 pA per amplifier), and a high output drive of 70 mA. They operate from a single supply of 5 V to 18 V and are specified for temperatures from –20 °C to +85 °C.
These amplifiers are available in 5‑lead SOT‑23, 14‑lead TSSOP, and 14‑lead SOIC surface‑mount packages. The document provides detailed electrical characteristics, absolute maximum ratings, thermal resistance data, and typical performance graphs.
