ADA4851-1YRJZ-RL7

Overview

The ADA4851-1YRJZ-RL7 is a single-channel, high-speed voltage feedback operational amplifier from Analog Devices. It features a 130 MHz bandwidth and a 375 V/μs slew rate. The device operates on a supply voltage range of 2.7 V to 12 V with a quiescent current of approximately 2.5 mA per amplifier. It offers rail-to-rail output capability, swinging within 60 mV of either supply rail. Key specifications include a low input offset voltage of 0.6 mV, an open-loop gain of 105 dB, and a common-mode rejection ratio of 105 dB.

Feature Summary

• High-speed performance with 130 MHz bandwidth and 375 V/μs slew rate for general-purpose applications
• Rail-to-rail output stage allowing signal swing within 60 mV of the supply rails
• Integrated power-down mode for reduced standby current consumption
• Low cost design with excellent video specifications including 0.08% differential gain

Applications

• Automotive infotainment systems
• Consumer video equipment
• Professional video switchers
• Active filters
• Clock buffers

Procurement Notes

Verify the specific package type and reel configuration when ordering. Confirm that the component meets automotive qualification requirements if intended for vehicle electronics. Check datasheet revisions for any updates to electrical characteristics or thermal resistance values before finalizing designs.

Selection Notes

Select this amplifier for applications requiring high speed and low cost in a small footprint. Consider the power-down feature for battery-operated devices. Ensure the load capacitance and drive requirements are within the specified limits to maintain stability and performance.

Part Context

This part belongs to the ADA4851 family, which includes single (ADA4851-1), dual (ADA4851-2), and quad (ADA4851-4) variants. The YRJZ suffix indicates a 6-lead SOT-23 package with tape and reel packaging. The family is designed for operation over an extended temperature range of -40°C to +125°C.

Replacement Considerations

Direct substitutes within the same family include ADA4851-2YRMZ and ADA4851-4YRUZ for dual and quad configurations respectively. Automotive qualified versions are available as ADA4851-1WYRJZ.
