AD8607ARZ-REEL

Overview

The AD8607ARZ-REEL is a dual-channel precision operational amplifier from Analog Devices, part of the AD8603/AD8607/AD8609 series. 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 a single supply from 1.8 V to 5 V or dual supplies from ±0.9 V to ±2.5 V, it consumes a maximum of 50 µA per amplifier. The device offers a gain bandwidth product of 400 kHz and unity gain stability.

Procurement Notes

Verify the specific ordering suffix matches the required package type and reel quantity. Confirm RoHS compliance status indicated by the Z suffix. Ensure the temperature range meets application requirements before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low power consumption alongside high precision. The dual-channel configuration suits space-constrained designs needing two independent amplifiers. Verify that the 400 kHz bandwidth meets signal frequency requirements.

Part Context

This device belongs to the AD860x family of micropower CMOS operational amplifiers. It shares core electrical characteristics with the single-channel AD8603 and quad-channel AD8609 variants. The family utilizes identical internal architecture optimized for low voltage portable electronics.

Replacement Considerations

Official substitutes within the same family include the AD8603 for single-channel needs and the AD8609 for quad-channel requirements. Cross-referencing pin compatibility and package dimensions is essential when substituting between different channel counts.

FAQ

Does the AD8607 exhibit phase reversal during overdrive conditions?

No, the AD8607 does not exhibit phase inversion even when the input voltage exceeds the maximum input common-mode voltage, handling voltages up to 1 V over the supply.

What is the maximum input bias current specification?

The maximum input bias current is specified as 1 pA at 25°C, increasing to 500 pA across the full operating temperature range of -40°C to +125°C.
