ADA4807-1ARJZ-R2

Overview

The ADA4807-1ARJZ-R2 is a single-channel, low noise, rail-to-rail input and output voltage feedback amplifier manufactured by Analog Devices. It combines high speed performance with DC precision, featuring a 180 MHz bandwidth and a 225 V/μs slew rate. The device operates on supply voltages ranging from 2.7 V to 11 V with a quiescent current of approximately 1 mA per amplifier. Key electrical specifications include an input voltage noise density of 3.1 nV/√Hz at 100 kHz, a maximum input offset voltage of ±125 μV, and a common-mode rejection ratio of 96 dB. It is housed in a 6-lead SOT-23 package.

Feature Summary

• Rail-to-rail input and output capability for maximum dynamic range
• Low power operation with 1 mA quiescent current per amplifier
• Integrated active-low disable pin for power-down control
• High slew rate and fast settling time for precise signal processing

Applications

• High resolution analog-to-digital converter (ADC) drivers
• Portable and battery-powered instruments and systems
• High component density data acquisition systems
• Audio signal conditioning
• Active filters

Procurement Notes

Verify the specific ordering suffix ARJZ-R2 against official documentation to confirm the package type and reel quantity. Ensure the design supports the required supply voltage range and thermal dissipation limits for the SOT-23 package. Confirm that the disable pin logic aligns with the system's power management strategy.

Selection Notes

Select this component when low noise and high speed are critical within a single-supply or dual-supply environment. The rail-to-rail I/O allows for optimal signal swing near the supply rails. Consider the integrated disable feature if power conservation during idle states is required. Verify compatibility with the target ADC input requirements regarding drive strength and settling time.

Part Context

This part belongs to the ADA4807 family, which includes single, dual, and quad variants. The family is designed for applications requiring low noise, high speed, and low power consumption. The ADA4807-1 variant specifically provides a single amplifier channel, making it suitable for space-constrained designs where only one channel is needed.

Replacement Considerations

Direct replacements within the same family include ADA4807-2ARMZ (dual) and ADA4807-4ARUZ (quad), provided pinout compatibility and channel count requirements are met. Cross-family replacements require careful evaluation of bandwidth, noise, and package dimensions.
