AD8607ARMZ

Overview

The AD8607ARMZ is a dual-channel precision micro-power operational amplifier from Analog Devices, housed in an 8-lead MSOP package. It features rail-to-rail input and output capabilities with a maximum offset voltage of 50 µV and low input bias current of 1 pA. Operating on single supplies from 1.8 V to 5 V or dual supplies from ±0.9 V to ±2.5 V, it consumes only 40 µA per amplifier. The device offers a gain bandwidth product of 400 kHz and unity gain stability.

Feature Summary

• Patented trimming technique achieves superior precision without laser adjustment
• Rail-to-rail input and output swing maximizes dynamic range in low voltage systems
• No phase reversal ensures stable operation even when input exceeds common-mode limits

Applications

• Battery-powered instrumentation
• Multipole filters
• Capacitive and inductive sensors
• Low power ASIC input or output amplifiers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging options and RoHS compliance status. Confirm that the selected variant matches the required temperature range and pin configuration for your design implementation.

Selection Notes

Select this component for designs requiring high precision in portable applications where low power consumption is critical. The dual-channel configuration suits differential signal processing. Ensure the PCB layout accommodates the 8-lead MSOP footprint and provides adequate thermal dissipation for the operating environment.

Part Context

This part belongs to the AD8603/AD8607/AD8609 family of precision CMOS operational amplifiers. While sharing core electrical characteristics like low noise and micropower operation, the AD8607 specifically provides two independent channels, distinguishing it from the single-channel AD8603 and quad-channel AD8609 variants within the same series.

Replacement Considerations

Direct functional replacements within the same family include the AD8607ARZ (SOIC package) or reel variants like AD8607ARMZ-REEL. Verify package compatibility and pinout alignment before substitution.

FAQ

Does the AD8607 exhibit phase reversal if the input voltage exceeds the supply rails?

No, the AD8607 does not exhibit phase reversal even when the input voltage exceeds the maximum input common-mode voltage by up to 1 V.

What is the typical supply current per amplifier channel?

The typical supply current is 40 µA per amplifier at room temperature, with a maximum specification of 50 µA.
