ADA4807-1AKSZ-R2

Overview

The ADA4807-1AKSZ-R2 is a single-channel, low noise, rail-to-rail input and output voltage feedback amplifier manufactured by Analog Devices Inc. It combines high speed performance with DC precision, featuring an 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 characteristics include a 3.1 nV/√Hz input voltage noise density, a maximum input offset voltage of ±125 μV, and a common-mode rejection ratio of 96 dB. It includes an active low power-down feature and functions reliably across an industrial temperature range of -40°C to +125°C.

Feature Summary

• Rail-to-rail input and output capabilities for maximum dynamic range in single-supply applications
• Ultra-low input voltage noise density of 3.1 nV/√Hz combined with high slew rate for precision signal processing
• Active low power-down mode significantly reduces quiescent current consumption when disabled
• Integrated disable circuitry allows for precise control over amplifier operation states

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 circuits
• Active filters

Procurement Notes

Verify the specific package type associated with the AKSZ suffix against official documentation before procurement. Confirm that the ordering suffix corresponds to the intended reel or cut tape configuration. Ensure compatibility with the required operating temperature range and supply voltage specifications for the target application environment.

Selection Notes

Select this component for designs requiring both high-speed signal integrity and low power consumption. The rail-to-rail I/O functionality makes it suitable for low-voltage single-supply systems. Consider the available packages, such as SOT-23 or SC70, based on board space constraints. Evaluate the disable pin requirements if power management during idle states is critical to the system design.

Part Context

This part belongs to the ADA4807 family, which includes single, dual, and quad channel variants. The series is designed to offer industry-leading low noise performance among high-speed rail-to-rail amplifiers. It serves as a solution for applications demanding high precision and fast settling times while maintaining low power dissipation, distinguishing it from standard operational amplifiers.

Replacement Considerations
