ADA4861-3YRZ-RL7

Overview

The ADA4861-3YRZ-RL7 is a high-speed, low-cost, 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. Key video performance metrics include 0.01% differential gain, 0.02° differential phase, and 0.1 dB flatness up to 100 MHz. It is housed in a 14-lead SOIC_N package and supports an extended operating temperature range of -40°C to +105°C.

Feature Summary

• High-speed current feedback architecture providing 730 MHz bandwidth and 625 V/µs slew rate for precise signal processing.
• Independent power-down control for each channel reduces quiescent current to 0.3 mA per amplifier when disabled.
• Optimized video performance characteristics including minimal differential gain and phase errors for accurate signal reproduction.
• Wide single or dual supply voltage operation capability supporting flexible system design requirements.

Applications

• Consumer video signal processing
• Professional video applications
• Broadband video transmission systems
• Analog-to-digital converter buffers

Procurement Notes

Verify the specific ordering suffix RL7 indicates a reel packaging quantity of 1,000 units as documented in the manufacturer's ordering guide. Confirm the Y designation corresponds to the Pb-free variant. Ensure compatibility with the specified 14-lead SOIC_N footprint during procurement planning.

Selection Notes

Select this component for designs requiring high bandwidth and low cost in multi-channel configurations. Consider the current feedback topology which requires external feedback resistors to set bandwidth. Evaluate the power-down feature if dynamic power management is required for battery-operated or thermally constrained environments.

Part Context

This part belongs to the ADA4861 series of triple amplifiers designed for high-speed analog signal processing. It serves as a cost-effective alternative to higher-priced precision amplifiers in applications where moderate DC accuracy is acceptable but high frequency response is critical. The series is widely used in video infrastructure and data acquisition systems.

Replacement Considerations

ADA4861-3YRZ is the non-reel equivalent offering identical electrical specifications and pinout compatibility within the same package family.
