ADA4858-3ACPZ-R2

Overview

The ADA4858-3 is a single-supply, high-speed triple current feedback amplifier featuring an integrated charge pump. This architecture eliminates the need for external negative supplies to output negative voltages or achieve a 0 V level, making it suitable for video applications. It operates on supply voltages from 3 V to 5.5 V with a total quiescent current of 42 mA. Key performance metrics include a 600 MHz bandwidth and 600 V/µs slew rate at +5 V. The device includes a power-down feature reducing current to 2.5 mA and offers a wide input common-mode range.

Feature Summary

• Integrated charge pump generates negative supply rail from single positive source
• High-speed current feedback architecture with 600 MHz bandwidth
• Power-down mode significantly reduces quiescent current consumption
• Wide input common-mode voltage range extending below ground

Applications

• Professional video signal processing
• Consumer video equipment drivers
• Imaging system interfaces
• Active filter circuits requiring high speed
