ADA4692-4ARUZ

Overview

The ADA4692-4ARUZ is a quad, low power, rail-to-rail output operational amplifier from Analog Devices. It features a 3.6 MHz gain bandwidth product and a typical supply current of 180 μA per amplifier. The device offers very low input bias currents of 0.5 pA and a voltage noise density of 16 nV/√Hz. It operates on single supplies from 2.7 V to 5 V or dual supplies from ±1.35 V to ±2.5 V. The part is housed in a 14-lead TSSOP package and functions without shutdown control.

Feature Summary

• Rail-to-rail output capability for maximum dynamic range
• Very low input bias current suitable for high impedance sources
• Low noise performance with minimal distortion
• Extended industrial temperature operation

Applications

• Photodiode amplifiers
• Sensor signal conditioning
• Portable audio equipment
• ADC drivers
• Active filters

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the exact package type and reel specifications. Ensure the component matches the required pin configuration and electrical characteristics for your design. Cross-reference the datasheet revision to confirm all parameters are current before finalizing procurement.

Selection Notes

Select this component when a quad amplifier configuration is required alongside low power consumption and rail-to-rail output swing. It is appropriate for applications demanding low noise and high input impedance without the need for individual channel shutdown control. Consider the 14-lead TSSOP package constraints during PCB layout.

Part Context

This device belongs to the ADA469x family of micropower operational amplifiers. Unlike the ADA4691 variant which includes shutdown pins, the ADA4692 series provides four independent amplifiers without power-down functionality. The family is designed for portable applications requiring extended battery life and high precision signal processing.

Replacement Considerations

The ADA4691-4ARUZ serves as a functional substitute within the same family, offering identical electrical performance but including dual shutdown pins for each pair of amplifiers. Verify that the additional shutdown logic does not interfere with the target circuit design.

FAQ

Does the ADA4692-4ARUZ include shutdown functionality?
