ADA4851-1YRJZ-R2

Overview

The ADA4851-1YRJZ-R2 is a single-channel, voltage feedback operational amplifier manufactured by Analog Devices Inc. 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 2.9 mA per amplifier. It provides rail-to-rail output capability, swinging within 60 mV of either supply rail. Key electrical parameters include an input offset voltage of 0.6 mV, an input bias current of 2.2 µA, and a short-circuit current of 125 mA sourcing and 110 mA sinking at ±5 V supplies.

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 swings within 60 mV of the supply rails.
• Integrated power-down mode that significantly reduces quiescent 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 suffix R2 indicates tape and reel packaging configuration. Confirm the component status as discontinued or obsolete through official Analog Devices channels before finalizing procurement plans. Ensure compatibility with existing PCB footprints for the SOT-23-6 package. Validate that the automotive grade variants are not required if operating in harsh environments.

Selection Notes

Select this component for designs requiring high speed and low cost in a compact surface-mount package. Consider the power-down feature for battery-operated applications where standby current reduction is critical. Evaluate the linear output current capabilities against load requirements to ensure adequate drive strength without distortion.

Part Context

This part belongs to the ADA4851 family, which includes dual (ADA4851-2) and quad (ADA4851-4) channel variants. The family shares similar electrical characteristics but differs in channel count and package options such as MSOP and TSSOP. The YRJZ suffix denotes the specific lead-free and RoHS-compliant version in the SOT-23-6 package.

Replacement Considerations

Direct substitutes within the same family include ADA4851-1ARJZ-R2 and ADA4851-1ARJZ-R7. Automotive qualified versions are available as ADA4851-1WYRJZ-R2. Verify pinout and thermal characteristics when transitioning between these variants.
