ADA4851-2WYRMZ-R7

Overview

The ADA4851-2WYRMZ-R7 is a dual-channel, high-speed voltage feedback operational amplifier with rail-to-rail output. It features a 130 MHz bandwidth and 375 V/µs slew rate. The device operates on supply voltages from 2.7 V to 12 V, drawing 2.5 mA per amplifier. It includes a power-down mode for low-power applications. Qualified for automotive use under AEC-Q100 standards, it functions within an extended temperature range of -40°C to +125°C. The component is housed in an 8-lead MSOP package.

Feature Summary

• Automotive grade qualification ensuring reliability in vehicle environments
• Rail-to-rail output capability allowing signal swing near supply rails
• Integrated power-down mode for significant current reduction
• High slew rate and wide bandwidth suitable for fast signal processing

Applications

• Automotive infotainment systems
• Automotive driver assistance systems
• Consumer video equipment
• Professional video switchers
• Active filters and clock buffers

Procurement Notes

Verify the specific ordering suffix matches the required packaging format. Confirm that the automotive grade designation aligns with project requirements. Ensure the pin configuration corresponds to the 8-lead MSOP layout. Check datasheet specifications against system operating conditions. Validate component authenticity through authorized distribution channels.

Selection Notes

Select this component when automotive qualification and high-speed performance are required simultaneously. Consider the rail-to-rail output for maximizing dynamic range in single-supply designs. Evaluate the power-down feature if energy efficiency during idle states is critical. Compare quiescent current consumption against other amplifiers in the same family.

Part Context

This part belongs to the ADA4851 family, which includes single (ADA4851-1), dual (ADA4851-2), and quad (ADA4851-4) variants. The 'W' suffix indicates automotive grade qualification, while 'YR' denotes the 8-lead MSOP package. The '-R7' suffix specifies tape and reel packaging. All variants share similar electrical characteristics but differ in channel count and package type.

Replacement Considerations

ADA4851-2YRMZ-R7 is the commercial grade equivalent without automotive qualification. ADA4851-1WYRMZ-R7 offers single-channel functionality in the same package. ADA4851-4WYRUZ-R7 provides four channels in a TSSOP package.
