AD8671ARMZ

Overview

The AD8671ARMZ is a single-channel precision operational amplifier manufactured by Analog Devices Inc. in an 8-lead MSOP package. It features a gain bandwidth product of 10 MHz, a slew rate of 4 V/µs, and a supply current of 3 mA per amplifier. The device operates within a temperature range of -40°C to +125°C with dual supplies from ±5 V to ±15 V. Key electrical specifications include a maximum input offset voltage of 75 µV, a maximum input bias current of 12 nA, and a minimum open-loop gain of 120 dB.

Feature Summary

• Unity-gain stable operation without phase reversal even when inputs exceed the supply rails.
• Capable of driving capacitive loads exceeding 1000 pF without instability.
• Designed for low power consumption while maintaining high precision and wide bandwidth.

Applications

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

Procurement Notes

Verify that the ordering suffix 'ARMZ' corresponds to the 8-lead MSOP package option as listed in the official Ordering Guide. Confirm RoHS compliance status associated with the 'Z' suffix. Ensure the component meets the extended industrial temperature range requirements specified for this part number.

Selection Notes

Select this component for applications requiring very low noise and high precision in a compact surface-mount footprint. The MSOP package offers half the board space of comparable amplifiers. Consider thermal resistance characteristics when designing for high ambient temperatures or multiple units on a single board.

Part Context

This device belongs to the AD8671/AD8672/AD8674 series of precision operational amplifiers. The series combines ultralow noise, high speed, and stability. While the AD8671 is a single-channel unit, the family includes dual (AD8672) and quad (AD8674) variants sharing similar electrical performance characteristics.
