ADA4841-1YRZ-R7

Overview

The ADA4841-1YRZ-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 per amplifier and operates within a supply voltage range of 2.7 V to 12 V. The device provides a wideband voltage noise density of 2.1 nV/√Hz and an input current noise of 1.4 pA/√Hz at 100 kHz. It offers a -3 dB bandwidth of 80 MHz (G = +1), a slew rate of 12 V/µs, and a settling time of 175 ns to 0.1%. The output swings rail-to-rail, reaching within 50 mV of either supply rail, while the input common-mode range extends down to the negative supply.

Feature Summary

• Rail-to-rail output capability extending within 50 mV of supply rails
• Low power operation with integrated power-down function
• High precision with low offset voltage and drift
• Capable of driving capacitive loads up to 10 pF

Applications

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

Procurement Notes

Verify that the ordering suffix R7 corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the component meets RoHS compliance standards as specified in the manufacturer's documentation. Ensure the selected package variant matches the PCB footprint design constraints before finalizing procurement orders.

Selection Notes

Select this amplifier when designing circuits requiring high linearity and low noise under strict power constraints. The device is suitable for applications needing rail-to-rail output swing on low voltage supplies. Consider the power-down feature for systems requiring extended battery life or reduced standby power consumption during inactive periods.

Part Context

This component belongs to the ADA4841 family of low power, low noise amplifiers manufactured by Analog Devices using the second generation XFCB process. The family includes dual-channel variants like the ADA4841-2. These amplifiers are designed for portable and industrial applications where precision and efficiency are critical requirements.

Replacement Considerations

The ADA4841-1YRZ is the non-reel version of this component. Other family members include the ADA4841-1YRJZ and ADA4841-1YRMZ.
