ADA4861-3YRZ-RL

Overview

The ADA4861-3YRZ-RL is a low-cost, high-speed, triple current feedback operational amplifier manufactured by Analog Devices Inc. It features a -3 dB bandwidth of 730 MHz and a slew rate of 625 V/µs. The device operates on supply voltages ranging from 5 V to 12 V with a quiescent current of 6 mA per amplifier. It includes independent power-down pins that reduce current consumption to 0.3 mA per amplifier when inactive. The component is housed in a 14-lead SOIC_N package and supports an extended operating temperature range from -40°C to +105°C.

Feature Summary

• Triple channel configuration with independent power-down control for each amplifier
• High-speed current feedback architecture supporting wide bandwidth applications
• Low voltage offset and high output current drive capability
• Wide single or dual supply voltage operation

Applications

• Consumer video signal processing
• Professional video line drivers
• Broadband video buffering
• Analog-to-digital converter (ADC) buffers
• Active filters

Procurement Notes

Verify the specific ordering suffix RL indicates reel packaging containing 2,500 units as documented in the manufacturer's ordering guide. Confirm the Y designation corresponds to the Pb-free variant. Ensure the selected part matches the required 14-lead SOIC_N physical dimensions and thermal characteristics for the target PCB layout.

Selection Notes

Select this component for designs requiring high-speed signal processing with multiple channels in a compact footprint. The current feedback topology offers consistent bandwidth regardless of gain settings within recommended limits. Consider the power-down feature for battery-operated systems where reducing standby current is critical. Verify that the PCB layout adheres to RF design techniques to maintain stability at high frequencies.

Part Context

This device belongs to the ADA4861 series of high-speed amplifiers. It serves as a triple-channel solution compared to single-channel variants like the ADA4860-1. The YRZ-RL suffix denotes the lead-free version packaged in a tape-and-reel format for automated assembly, distinct from the tube-packaged standard version.
