ADA4862-3YRZ-RL

Overview

The ADA4862-3YRZ-RL is a low-cost, high-speed triple operational amplifier manufactured by Analog Devices Inc. It features an internally fixed gain of G = +2 with on-chip feedback resistors, simplifying circuit design and reducing board space. The device supports operation at supply voltages ranging from 5 V to 12 V (single or dual supply) and operates within an extended temperature range of -40°C to +105°C. Key electrical specifications include a -3 dB bandwidth of 300 MHz at +5 V supply, 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 independent power-down pins for each channel to reduce quiescent current to 200 µA per amplifier when inactive.

Feature Summary

• Integrates internal fixed-gain resistors to eliminate external components and minimize board area.
• Provides independent power-down control for each amplifier channel to lower power consumption.
• Supports configurable operation in gains of +1 and -1 despite the internal fixed G = +2 architecture.
• Optimized for video applications with low differential gain and phase errors.

Applications

• Consumer video signal processing
• Professional video line drivers
• RGB/HD/SD video buffering

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as the YRZ-RL designation indicates reel packaging. Confirm the component is lead-free (Pb-free) if environmental compliance is mandatory for the assembly process. Ensure the voltage rating and thermal dissipation limits are respected during PCB layout to maintain reliability under maximum load conditions.

Selection Notes

Select this component when a triple-channel amplifier with fixed gain is required to simplify schematic design and reduce bill-of-materials count. It is suitable for designs needing high speed and low distortion without the complexity of external gain-setting networks. Consider the power-down feature if system-level energy efficiency is critical during idle states.

Part Context

This part belongs to the ADA4862 series of high-speed, low-cost triple operational amplifiers. The series is designed specifically for video applications requiring precise signal integrity. The YRZ variant denotes the 14-lead SOIC package with lead-free termination, while the -RL suffix specifies the reel packaging option for automated surface-mount assembly.
