AD8674ARUZ

Overview

The AD8674ARUZ 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 operates on dual supplies ranging from ±5 V to ±15 V with a maximum supply voltage of 36 V. Key electrical characteristics include an input offset voltage of 20 µV (max 75 µV), input bias current of 12 nA, and voltage noise density of 2.8 nV/√Hz. It maintains unity-gain stability and supports capacitive loads exceeding 1000 pF.

Feature Summary

• Combines ultralow noise, high precision, speed, and stability for unmatched performance.
• Outputs remain stable when driving capacitive loads greater than 1000 pF.
• Operates without output phase reversal even when the input voltage exceeds the supply rails by 1 V.
• Designed for low power consumption while maintaining wide bandwidth.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance details such as RoHS status. Ensure the selected package variant matches the required thermal resistance and pin configuration for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to validate all absolute maximum ratings and operating temperature ranges before finalizing procurement specifications.

Selection Notes

Select this component for applications requiring very low noise and high precision within a quad configuration. Consider the 14-lead TSSOP package dimensions and thermal characteristics during board design. Evaluate the trade-off between the 3 mA typical supply current per amplifier and the system's power budget. Verify that the 10 MHz bandwidth meets the signal processing requirements for the intended frequency range.

Part Context

This part belongs to the AD8671/AD8672/AD8674 series of precision amplifiers. While the AD8671 and AD8672 are specified over an extended industrial temperature range (-40°C to +125°C), the AD8674 is rated for the standard industrial range (-40°C to +85°C). All variants share identical electrical performance characteristics regarding noise, bandwidth, and drive capability.
