AD8607ARM-REEL

Overview

The AD8607ARM-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 low offset voltage (50 µV max) and low noise (22 nV/√Hz). 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 channel. The device utilizes patented trimming for high accuracy without laser adjustment. Packaged in an 8-lead MSOP, it supports operation from -40°C to +125°C.

Feature Summary

• Patented trimming technique achieves superior precision without laser trimming
• Rail-to-rail input and output swing capability
• No phase reversal even when input exceeds common-mode range
• Unity gain stable with micropower consumption

Applications

• Battery-powered instrumentation
• Multipole filters
• Proximity sensors
• Photodiode amplification
• Low power ASIC input or output amplifiers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct package type and reel quantity specifications. Confirm RoHS compliance status as indicated by the Z suffix in the official ordering guide. Cross-reference the temperature range and pin configuration with the datasheet outline dimensions before procurement.

Selection Notes

Select this component for applications requiring low power consumption alongside high precision and low noise performance. The dual-channel configuration in an 8-lead MSOP package is suitable for space-constrained designs. Ensure the supply voltage remains within the specified 1.8 V to 5 V range for optimal electrical characteristics and stability.

Part Context

This device belongs to the AD8603/AD8607/AD8609 family of precision micro-power CMOS operational amplifiers. The AD8607 specifically provides two channels in an 8-lead package, distinguishing it from the single-channel AD8603 and quad-channel AD8609. All members share identical core electrical specifications and trimming technology.

Replacement Considerations

Official substitutes within the same family include the AD8603 for single-channel needs and the AD8609 for quad-channel requirements. Other variants such as AD8607ARZ offer the same electrical performance in an SOIC package instead of MSOP.

FAQ

Does the AD8607 exhibit phase reversal if the input voltage exceeds the maximum common-mode voltage?

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 for the AD8607?

The maximum input bias current is 1 pA at 25°C, increasing to 50 pA between -40°C and +85°C, and 500 pA between -40°C and +125°C.
