ADA4862-3YRZ

Overview

The ADA4862-3YRZ is a triple, low-cost, high-speed operational amplifier manufactured by Analog Devices Inc. It features internally fixed feedback resistors providing a default gain of G = +2, with configurable options for G = +1 and G = -1. The device operates within a supply voltage range of 5 V to 12 V (single or dual supplies). Key electrical parameters include a -3 dB bandwidth of 300 MHz at G = +2, a slew rate of 750 V/µs, and a settling time of 9 ns to 0.5%. It delivers a typical output current of 25 mA and includes an independent power-down feature for each channel to reduce quiescent current consumption.

Feature Summary

• Integrates on-chip feedback and gain-setting resistors to simplify circuit design and minimize board space requirements.
• Provides independent power-down control for each amplifier channel to significantly reduce power consumption when inactive.
• Optimized for video applications with excellent differential gain and phase performance supporting high-definition resolutions.

Applications

• Consumer video signal processing
• Professional video line drivers
• Video filter buffers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and temperature rating. Confirm that the component meets RoHS compliance standards as indicated in the datasheet. Check for availability status through authorized distributors, as supply levels may vary. Ensure the selected variant matches the required PCB footprint for the 14-lead SOIC package.

Selection Notes

Select this component for designs requiring high-speed amplification with minimal external passive components due to internal gain setting. Consider the power-down functionality if system-level energy efficiency is critical. Evaluate the 14-lead SOIC package constraints regarding thermal dissipation and layout density. Verify that the input common-mode voltage range and output swing capabilities align with the specific signal levels of the application.

Part Context

This part belongs to the ADA4862 series of high-speed operational amplifiers designed by Analog Devices. It is specifically engineered for cost-sensitive video applications where board space and assembly complexity are concerns. The integration of internal resistors distinguishes it from standard op-amps that require external gain-setting networks.
