ADA4860-1YRJZ-RL7

Overview

The ADA4860-1YRJZ-RL7 is a low-cost, high-speed current feedback operational amplifier manufactured by Analog Devices Inc. It features an 800 MHz -3 dB bandwidth and a 790 V/μs slew rate. The device operates on supply voltages ranging from 5 V to 12 V with a typical quiescent current of 6 mA. It includes a power-down feature that reduces current consumption to 0.25 mA. Key performance metrics include an 8 ns settling time to 0.5%, 0.02% differential gain, and 0.02° differential phase. The component is housed in a 6-lead SOT-23 package and supports an operating temperature range of -40°C to +105°C.

• Analog-to-digital converter (ADC) input buffering
• Active filter circuits

Procurement Notes

Verify the specific ordering suffix YRJZ-RL7 against official manufacturer documentation to confirm the exact reel packaging configuration and tape specifications. Ensure compatibility with existing surface-mount assembly processes for the 6-lead SOT-23 footprint. Cross-reference the part number with the latest datasheet revision to confirm parameter stability and availability status before finalizing procurement plans.

Selection Notes

Select this component for applications requiring high-speed voltage conversion with low cost constraints. The current feedback topology offers bandwidth independence from closed-loop gain, making it suitable for variable gain stages. Consider the power-down pin if system-level energy efficiency is critical during idle periods. Evaluate PCB layout requirements carefully to minimize parasitic capacitance at the summing junction for optimal frequency response.

Part Context

This device belongs to the ADA4860 series of high-speed operational amplifiers designed by Analog Devices. The series focuses on providing cost-effective solutions for video and broadband applications without compromising speed or dynamic performance. The single-channel configuration distinguishes it from dual or triple variants within the same family, offering a compact solution for space-constrained designs.

Replacement Considerations

Consult the manufacturer's official replacement guide for verified substitute part numbers. Ensure any alternative maintains the 6-lead SOT-23 package and compatible pinout to avoid redesigning the printed circuit board. Verify that electrical parameters such as bandwidth and slew rate meet or exceed the original specifications.

FAQ

How does the power-down pin function?

The power-down pin reduces the quiescent supply current when the amplifier is not in use. The amplifier powers down when the voltage applied to this pin exceeds the negative supply voltage plus 0.5 V. If unused, the pin should be connected to the negative supply.

What is the recommended feedback resistor value for a gain of +2?

For a non-inverting gain of +2, the recommended feedback resistor (RF) and gain-setting resistor (RG) values are both 499 Ω.

Is the ADA4860-1 rail-to-rail output?

No, the ADA4860-1 does not have rail-to-rail output capability. The output voltage swing is limited by the supply rails and load conditions.
