ADA4692-4ARUZ

Overview

The ADA4692-4ARUZ is a quad, low-power, voltage-feedback operational amplifier manufactured by UMW. It features rail-to-rail output capability and operates on single supplies from 2.7 V to 5 V or dual supplies of ±1.35 V to ±2.5 V. Key electrical specifications include a gain bandwidth product of 3.6 MHz, a typical supply current of 180 μA per amplifier, and an input bias current as low as 0.5 pA. The device offers a typical offset voltage of 500 μV with a maximum drift of 4 μV/°C and a voltage noise density of 16 nV/√Hz at 1 kHz.

Feature Summary

• Rail-to-rail output stage enables full signal swing across the supply range for single-supply applications.
• Ultra-low input bias current of 0.5 pA typical supports high-impedance sensor interfacing.
• Low power consumption of 180 μA per channel extends battery life in portable devices.
• Low distortion characteristics (0.003% THD+N) suitable for precision audio processing.

Applications

• Photodiode amplifiers
• Portable medical instrumentation
• Active filters
• ADC drivers

Procurement Notes

Verify that the component matches the specific quad configuration without shutdown functionality. Confirm the package type is TSSOP-14 and check for RoHS compliance status. Ensure the manufacturer designation corresponds to UMW rather than other vendors producing similar part numbers.

Selection Notes

Select this component when low power consumption and rail-to-rail output are required in a quad configuration. It is suitable for applications needing low input bias current and moderate bandwidth. Note that this specific variant lacks a shutdown pin; use the dual version if shutdown control is necessary.

Part Context

This component belongs to the ADA4692 series of low-power, rail-to-rail output operational amplifiers. The quad version provides four independent amplifiers in a single package, offering a compact solution for multi-channel signal conditioning tasks compared to using multiple dual amplifiers.

Replacement Considerations

Check for direct substitutes such as the ADA4692-4ARZ-RL or equivalent quad op-amps with matching 3.6 MHz bandwidth and rail-to-rail output capabilities. Verify pinout compatibility and electrical parameter alignment before substitution.

FAQ

Does the ADA4692-4ARUZ have a shutdown feature?

No, the ADA4692-4 is the quad version without a shutdown pin. The dual version (ADA4692-2) includes shutdown functionality.

What is the typical input bias current?

The typical input bias current is 0.5 pA, which increases to a maximum of 360 pA over the extended temperature range.
