AD8634HRZN

Overview

The UMW AD8634HRZN is a quad, low-noise, micro-power CMOS operational amplifier. It features a gain bandwidth product of 6.5MHz and a slew rate of 4V/µs. The quiescent current is 480µA per amplifier at 5V. Maximum input offset voltage is 4.2mV with a drift of 2µV/°C. Input noise density is 20nV/√Hz at 10kHz. Open-loop gain reaches 103dB. Operating supply voltage ranges from +2.3V to +5.5V. The device supports rail-to-rail input and output swing. It operates over an extended industrial temperature range of -40°C to +125°C.

Feature Summary

Rail-to-rail input and output capability for maximum dynamic range
Low power consumption with 480µA quiescent current per amplifier
High open-loop gain of 103dB suitable for active filter applications
Unit-gain stable design ensuring stability in buffer configurations

Applications

Photodiode amplification circuits
Sensor interface conditioning
Audio output stages
Active filter designs
Driving analog-to-digital converters

Procurement Notes

Verify the package marking matches the TSSOP-14 specification. Confirm the suffix HRZN corresponds to the tape and reel delivery mode as listed in ordering information. Ensure the component date code aligns with production requirements. Check for physical damage to pins before soldering. Validate that the supplier provides traceability documentation consistent with UMT Semiconductor manufacturing standards.

Selection Notes

Select this component when multiple channels are required in a single package. The quad configuration reduces board space compared to individual single or dual units. Consider the 480µA current draw for battery life calculations. Verify that the 6.5MHz bandwidth meets the signal frequency requirements. Ensure the 4.2mV maximum offset voltage fits the precision needs of the application circuit.

Part Context

This part belongs to the AD863xA family, which includes single (AD8631A), dual (AD8632A), and quad (AD8634A) variants. All members share identical electrical characteristics and pinouts where applicable. The family is designed for low voltage and low noise systems. The quad version integrates four independent amplifiers into one 14-lead package.

Replacement Considerations

Direct functional substitutes within the same family include AD8631ARZ and AD8632ARZ. Cross-package replacements require verifying pin compatibility between TSSOP-14 and SOIC-14. Other manufacturers' parts must be evaluated against the 6.5MHz bandwidth and 480µA current specifications.
