AD8674ARUZ-REEL

Overview

The AD8674ARUZ-REEL is a quad precision operational amplifier from Analog Devices, housed in a 14-lead TSSOP package. It features a gain bandwidth product of 10 MHz and a slew rate of 4 V/µs. The device exhibits a maximum input offset voltage of 75 µV and an input bias current of 12 nA. Supply current is typically 3 mA per amplifier at 30 V. Operating temperature range is -40°C to +85°C.

Feature Summary

• Very low noise performance with 2.8 nV/√Hz density
• High open-loop gain of 120 dB minimum
• Stable operation with capacitive loads exceeding 1000 pF
• No phase reversal when inputs exceed supply rails

Applications

• PLL filters
• Filters for GPS
• Instrumentation
• Sensors and controls
• Professional quality audio

Procurement Notes

Verify the specific suffix 'REEL' indicates tape and reel packaging configuration. Confirm the 'Z' suffix denotes RoHS compliance status as defined by the manufacturer. Ensure the ordering code matches the exact quad channel variant required for the design.

Selection Notes

Select this component for applications requiring high precision and low noise without excessive power consumption. Consider the industrial temperature range limits (-40°C to +85°C) against environmental requirements. Evaluate the 14-lead TSSOP footprint constraints relative to available board space.

Part Context

This part belongs to the AD8671/AD8672/AD8674 series of very low noise, low input bias current operational amplifiers. The AD8674 specifically provides four independent channels within a single integrated circuit, offering a compact solution for multi-channel signal processing tasks compared to using discrete single or dual units.

Replacement Considerations

Consult official documentation for direct pin-compatible substitutes within the same family, such as AD8674ARZ or AD8674ARU, noting differences in package type or temperature rating.
