ADA4692-2ACPZ-RL

Overview

The ADA4692-2ACPZ-RL is a dual, low power, wideband, low noise, rail-to-rail output operational amplifier from Analog Devices. It features a typical supply current of 180 μA per amplifier and very low input bias currents of 0.5 pA. The device offers a gain bandwidth product of 3.6 MHz, a typical offset voltage of 500 μV, and a maximum offset voltage drift of 4 μV/°C. It operates on a single supply from 2.7 V to 5 V or dual supplies from ±1.35 V to ±2.5 V. The component is housed in an 8-lead LFCSP package.

Feature Summary

• Rail-to-rail output capability for maximizing dynamic range
• Low power consumption with minimal supply current draw
• Very low input bias current suitable for high impedance sources
• Low noise performance optimized for precision signal processing

Applications

• Photodiode amplifiers
• Sensor amplifiers
• Portable audio devices
• ADC drivers
• Active filters

Procurement Notes

Verify the specific ordering suffix ACPZ-RL against the manufacturer's official documentation to confirm the package type and reel packaging configuration. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision to validate electrical characteristics before finalizing procurement specifications.

Selection Notes

Select this component when designing circuits that require low power operation combined with wide bandwidth and low noise. It is suitable for applications needing rail-to-rail output swing without the shutdown functionality found in the ADA4691-2 variant. Consider the 8-lead LFCSP package for compact board layouts requiring small footprint solutions.

Part Context

This part belongs to the ADA469x family of micropower operational amplifiers manufactured by Analog Devices. The family includes dual (ADA4691-2, ADA4692-2) and quad (ADA4691-4, ADA4692-4) versions. The ADA4692-2 specifically lacks the shutdown pins present in the ADA4691-2, offering a simpler interface while maintaining identical core electrical performance characteristics.

Replacement Considerations

The ADA4691-2 serves as a functional substitute if shutdown control is not required, though it includes additional pins. Other members of the ADA469x family may be considered based on channel count requirements.
