ADA4862-3YRZ-RL7

Overview

The ADA4862-3YRZ-RL7 is a triple, low-cost, high-speed operational amplifier manufactured by Analog Devices Inc. It features an internally fixed gain of G = +2 with on-chip feedback resistors, eliminating the need for external components and minimizing board space. The device offers a -3 dB bandwidth of 300 MHz at +5 V supply and 310 MHz at ±5 V supply, alongside a slew rate of 750 V/µs. It supports differential gains of 0.02% and phases of 0.03°, making it suitable for video applications. Operating within a supply range of 5 V to 12 V, each amplifier draws 5.3 mA quiescent current, which can be reduced to 200 µA via independent power-down pins. It is housed in a 14-lead SOIC package.

Feature Summary

• Integrates internal fixed-gain resistors to simplify circuit design and reduce component count.
• Provides independent power-down control for each channel to minimize active power consumption.
• Delivers high-speed performance with wide bandwidth and fast settling times for signal fidelity.
• Supports configurable operation for unity gain (+1) and inverting gain (-1) configurations.

Applications

• Consumer and professional RGB/HD/SD video drivers
• Video line drivers supporting 1080i and 720p resolutions
• Filter buffers in high-speed signal processing chains

Procurement Notes

Verify that the ordering suffix RL7 corresponds to the 1000-unit reel packaging option as specified in the manufacturer's ordering guide. Confirm the part number includes the Z suffix to ensure compliance with lead-free manufacturing standards. Cross-reference the specific revision A datasheet to validate electrical parameters against your system requirements before finalizing procurement decisions.

Selection Notes

Select this component when a cost-effective solution is required for multi-channel video signal processing. The integrated feedback network reduces layout complexity compared to discrete resistor designs. Ensure the application benefits from the available power-down feature for thermal management or standby modes. Verify that the 14-lead SOIC package dimensions fit the target PCB footprint constraints.

Part Context

This device belongs to the ADA4862 family of high-speed amplifiers designed specifically for video applications. It distinguishes itself through the integration of internal gain-setting resistors, which simplifies the bill of materials and improves consistency across production runs. The triple configuration allows for efficient handling of RGB color channels or multiple signal paths within a single package.

Replacement Considerations

Direct substitutes include other parts from the ADA4862 series, such as the ADA4862-3YRUZ, provided the package type and temperature range are compatible. Verify pinout compatibility and electrical specifications before swapping components to ensure circuit stability.
