This document describes the features and characteristics of the ADA4858-3, a single-supply, high-speed, triple op amp with a charge pump. It features an integrated charge pump, wide supply range, high-speed amplifiers, low power consumption, etc.
The ADA4858-3 is a triple operational amplifier designed for video and high‑speed applications. It operates from a single supply of 3 V to 5.5 V and includes an integrated charge pump that eliminates the need for a negative supply.
Key features include a 600 MHz –3 dB bandwidth, 600 V/µs slew rate, low quiescent current of 42 mA (down to 2.5 mA in power‑down), and a maximum external output current of 50 mA at –3 V. The device is offered in a 16‑lead LFCSP package and is rated for –40 °C to +105 °C operation.
