ADA4858-3ACPZ-RL

Overview

The ADA4858-3 is a single-supply, high-speed triple current feedback operational amplifier featuring an integrated charge pump. It operates on supply voltages from 3 V to 5.5 V and generates a negative rail for video applications. Key specifications include a 600 MHz bandwidth, 600 V/µs slew rate, and 18 ns settling time. The device consumes 42 mA total quiescent current and includes a power-down feature reducing consumption to 2.5 mA. It is housed in a 16-lead LFCSP package.

Feature Summary

• Integrated charge pump eliminates the need for external negative supplies
• High-speed performance with 600 MHz bandwidth and 600 V/µs slew rate
• Power-down pin reduces total quiescent current significantly
• Wide input common-mode voltage range extending below ground

Applications

• Professional video signal processing
• Consumer video equipment
• Imaging systems
• Active filter circuits

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm packaging type and reel specifications. Confirm RoHS compliance status and lead-free availability through authorized distributors or the manufacturer directly before finalizing procurement plans.

Selection Notes

Select this component for designs requiring high-speed amplification without dual power supplies. The integrated charge pump simplifies board layout by removing negative rails. Ensure adequate bypassing near power pins and consider thermal dissipation limits when operating at maximum ambient temperatures within the specified industrial range.

Part Context

This part belongs to Analog Devices' high-speed operational amplifier family. It is specifically engineered for video applications where single-supply operation and high bandwidth are critical. The triple configuration allows for efficient handling of multiple video channels or color components within a compact footprint.

Replacement Considerations

Consult the manufacturer's datasheet for officially listed replacement parts or updated revisions. Verify pin compatibility and electrical specifications if substituting with other models from the same product line.
