ADA4841-1YRJZ-R2

Overview

The ADA4841-1YRJZ-R2 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 a typical operating current of 1.1 mA. The device offers a wide supply voltage range of 2.7 V to 12 V and operates within an industrial temperature range of -40°C to +125°C. Key electrical specifications include a gain-bandwidth product of 80 MHz, a slew rate of 12 V/µs, and a maximum input offset voltage of 300 µV. Noise performance is characterized by 2.1 nV/√Hz voltage noise and 1.4 pA/√Hz current noise at 100 kHz.

Feature Summary

• Rail-to-rail output capability allows signal swing to within 50 mV of either supply rail.
• Integrated power-down function significantly reduces supply current when disabled.
• Low distortion characteristics support high-resolution data acquisition systems.
• 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 package marking and date code against the manufacturer's latest ordering guide before implementation. Confirm that the reel packaging matches the required quantity for production runs. Ensure ESD handling protocols are followed during storage and assembly. Cross-reference the RoHS compliance status with current regulatory requirements for the target market.

Selection Notes

Select this component for applications requiring precision amplification with strict power constraints. The low noise density makes it suitable for high-resolution signal chains. Consider the power-down feature if battery life extension is critical. Verify that the 80 MHz bandwidth meets the system's frequency response requirements without excessive gain peaking.

FAQ

How does the power-down pin affect the quiescent current?

When the power-down pin is driven to the specified logic level, the quiescent current drops significantly, often to below 100 µA, depending on the supply voltage.

What is the input common-mode voltage range?

The input common-mode voltage range extends down to the negative supply rail, allowing for full differential input operation even in single-supply configurations.
