AD8607ARZ-REEL7

Overview

The AD8607ARZ-REEL7 is a dual-channel precision operational amplifier from Analog Devices, featuring rail-to-rail input and output capabilities. It operates on a single supply of 1.8 V to 5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical specifications include a maximum offset voltage of 50 µV, a gain bandwidth product of 400 kHz, and a typical supply current of 40 µA per amplifier. The device utilizes a patented trimming technique for high accuracy without laser adjustment.

Feature Summary

• Patented trimming technology achieves superior precision without requiring laser adjustment.
• Rail-to-rail input and output swing capability enables buffering of wide-swing devices in low-power systems.
• Operates without phase reversal even when input voltages exceed the common-mode range.
• Unity gain stable with low distortion characteristics suitable for precision applications.

Applications

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

Procurement Notes

Verify the specific package option and reel quantity against the official ordering guide. Confirm RoHS compliance status as indicated by the suffix. Ensure the operating temperature range matches the application requirements before procurement.

Selection Notes

Select this component for applications requiring low power consumption alongside high precision. The dual-channel configuration is ideal for space-constrained designs needing two independent amplifiers. Consider the rail-to-rail performance for single-supply systems interfacing with CMOS ADCs or DACs.

Part Context

This part belongs to the AD8603/AD8607/AD8609 family of precision micropower amplifiers. The AD8607 specifically provides a dual-channel configuration, whereas the AD8603 offers a single channel and the AD8609 provides four channels. All share similar electrical characteristics and packaging options within the series.

Replacement Considerations

Official substitutes within the same family include the AD8603 for single-channel needs and the AD8609 for quad-channel requirements. Ensure the replacement maintains the required channel count and package compatibility for direct integration.

FAQ

Does the AD8607 exhibit phase reversal?

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

What is the maximum input bias current?

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