ADA4851-1YRJZ-RL

Overview

The ADA4851-1YRJZ-RL is a single-channel, high-speed voltage feedback operational amplifier manufactured by Analog Devices Inc. It features a 130 MHz gain-bandwidth product and a 375 V/μs slew rate. The device operates within a supply voltage range of 2.7 V to 12 V and consumes approximately 2.9 mA per amplifier. It offers rail-to-rail output capability, swinging within 60 mV of either supply rail. Key specifications include a typical input offset voltage of 0.6 mV, an open-loop gain of 107 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 capable of swinging within 60 mV of the supply rails
• Integrated power-down mode for reduced current consumption when disabled
• Low input offset voltage and low noise characteristics suitable for precision signal processing

Applications

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

Procurement Notes

Verify the specific ordering suffix RL indicates tape and reel packaging configuration. Confirm the YRJZ designation corresponds to the 6-lead SOT-23 package variant. Ensure compatibility with the intended supply voltage range and temperature operating conditions specified in the datasheet before finalizing procurement.

Selection Notes

Select this component for designs requiring high slew rates and wide bandwidth in a compact surface-mount package. Consider the power-down feature if system-level power management is required. Evaluate thermal resistance constraints for the SOT-23 package under maximum load conditions. Verify that the input common-mode voltage range meets the application's signal requirements relative to the negative supply rail.

Part Context

This part belongs to the ADA4851 family, which includes single (ADA4851-1), dual (ADA4851-2), and quad (ADA4851-4) channel variants. The family is designed for low-cost, high-speed applications. The YRJZ suffix specifically denotes the single-channel version housed in a 6-lead SOT-23 package, distinguishing it from the MSOP and TSSOP options available in the series.

FAQ

Does the ADA4851-1 support true single-supply operation?

Yes, the device supports true single-supply operation, allowing input signals to extend 200 mV below the negative rail.

What is the purpose of the POWER DOWN pin?

The POWER DOWN pin allows the user to reduce the quiescent current significantly when the amplifier is not in use.
