This document describes ADA4858-3, a single-supply, high-speed, triple op amp with a charge pump. It features an integrated charge pump, a supply range of 3V to 5.5V, an output range of -3.3V to -1.8V, and a maximum external output current of 50mA at -3V, etc.
The ADA4858-3 is a single‑supply, high‑speed current‑feedback amplifier featuring an integrated charge pump, eliminating the need for negative supplies. It operates from 3 V to 5.5 V and delivers up to 600 MHz bandwidth and 600 V/µs slew rate, making it suitable for professional and consumer video applications.
The device is offered in a 16‑lead LFCSP package, supports a wide input common‑mode range, and includes a power‑down pin that reduces quiescent current to as low as 2.5 mA. Detailed specifications, pin functions, and typical performance graphs are provided in the document.
