Overview
The AD8672ARM-R2 is a dual-channel precision operational amplifier from Analog Devices, housed in an 8-lead MSOP package. It features a gain bandwidth product of 10 MHz and a slew rate of 4 V/µs. Key electrical parameters include a maximum input offset voltage of 75 µV, a minimum open-loop gain of 120 dB, and a typical supply current of 3 mA per amplifier. The device operates on dual supplies ranging from ±5 V to ±15 V and supports an extended industrial temperature range of -40°C to +125°C.
Feature Summary
- Very low noise performance with 2.8 nV/√Hz density
- Unity-gain stable operation without phase reversal
- Capacitive load stability exceeding 1000 pF
Applications
- PLL filters
- Filters for GPS
- Instrumentation
- Sensors and controls
- Professional quality audio
Procurement Notes
Verify the specific ordering suffix R2 against official documentation to confirm tape and reel packaging requirements. Ensure the component meets RoHS compliance standards as indicated by the Z suffix in related part numbers. Confirm that the 8-lead MSOP package option aligns with board space constraints and thermal management needs for the target application environment.
Selection Notes
Select this component when high precision and low noise are critical alongside moderate bandwidth requirements. The dual-channel configuration allows for cost-effective implementation of differential circuits or multi-stage filtering within a compact footprint. Consider the extended temperature range suitability for demanding industrial environments where stability under varying thermal conditions is required.
Part Context
This device belongs to the AD8671/AD8672/AD8674 series of very high precision amplifiers designed for applications requiring ultralow noise, high speed, and stability. The AD8672 specifically provides two independent channels in a single package, offering half the board space of comparable amplifiers while maintaining identical electrical characteristics to its single-channel counterpart.
Replacement Considerations
Check for AD8672ARZ or AD8672ARMZ equivalents if different packaging formats are needed. Verify pin compatibility and electrical specifications against other dual-channel precision op-amps in the Analog Devices portfolio before substitution.
