ADA4841-1YRJZ-R7

Overview

The ADA4841-1YRJZ-R7 is a single-channel, unity-gain stable operational amplifier from Analog Devices. It features low power consumption with a maximum quiescent current of 1.5 mA and a typical operating current of 1.1 mA per amplifier. The device offers a gain-bandwidth product of 80 MHz at a gain of +1 and a slew rate of 12 V/µs. Input noise performance includes 2.1 nV/√Hz voltage noise and 1.4 pA/√Hz current noise. It supports a wide supply range from 2.7 V to 12 V and operates within an industrial temperature range of -40°C to +125°C. The output swings rail-to-rail, reaching within 50 mV of either supply rail.

Feature Summary

• Rail-to-rail output capability allows signal swing to within 50 mV of the supply rails.
• Integrated power-down function significantly reduces quiescent current when disabled.
• Low distortion characteristics ensure high linearity for precision signal processing.
• Capable of driving capacitive loads up to 10 pF with minimal peaking.

Applications

• Battery-powered instrumentation
• 16-bit PulSAR ADC drivers
• Low power, low noise signal processing

Procurement Notes

Verify the specific suffix 'R7' indicates tape and reel packaging configuration. Confirm the 'YRJZ' designation corresponds to the SOT-23-6 package variant. Ensure the component meets RoHS compliance requirements as specified in the manufacturer documentation. Cross-reference the ordering guide for availability status.

Selection Notes

Select this component for applications requiring low noise and low power simultaneously. The rail-to-rail output is suitable for single-supply systems. Consider the power-down feature for battery-operated devices. Verify that the 80 MHz bandwidth meets the system speed requirements.

Part Context

This part belongs to the ADA4841 family of low power, low noise amplifiers. The '-1' suffix denotes a single-channel configuration. The 'YRJZ' code identifies the SOT-23-6 surface-mount package. The 'R7' suffix specifies the reel packaging format for automated assembly processes.

Replacement Considerations

ADA4841-1YRZ-RL is a compatible alternative in SOIC-8 packaging.

FAQ

Does the ADA4841-1YRJZ-R7 have a shutdown mode?

Yes, the ADA4841-1 includes a dedicated power-down pin to reduce quiescent current.
