AD8614/AD8644 are single and quad 18 V operational amplifiers with a unity-gain bandwidth of 5.5 MHz, low voltage offset of 1.0 mV, slew rate of 7.5 V/μs, single-supply operation from 5V to 18V, high output current of 70 mA, low supply current of 800 μA/amplifier, stability with large capacitive loads, and rail-to-rail inputs and outputs.
The AD8614 (single) and AD8644 (quad) are single‑supply, rail‑to‑rail operational amplifiers optimized for LCD monitor applications. They operate from 5 V to 18 V, deliver up to 70 mA output current, and feature a 5.5 MHz unity‑gain bandwidth with a 7.5 V/µs slew rate. The devices are built on Analog Devices' high‑voltage extra‑fast complementary bipolar (HV XFCB) process, providing low supply current (800 µA per amplifier) and robust capacitive‑load drive.
The datasheet includes detailed electrical characteristics, absolute maximum ratings, thermal resistance data, and protection guidelines such as input over‑voltage and output short‑circuit protection. Package options are offered in 5‑lead SOT‑23, 14‑lead TSSOP and 14‑lead SOIC formats, with ordering information and recommended unused‑amplifier configurations.
