AD8601ARTZ-REEL7

Overview

The AD8601ARTZ-REEL7 is a single-channel, precision CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a gain bandwidth product of 8.4 MHz and a slew rate of 6 V/µs at 5V supply. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing a typical supply current of 750 µA. Key electrical specifications include a maximum input offset voltage of 500 µV (A Grade) and an input bias current as low as 0.2 pA. It is housed in a 5-lead SOT-23 package.

Feature Summary

• Utilizes patented DigiTrim technology for post-package trimming without laser adjustment.
• Features true rail-to-rail input and output architecture extending to both supply rails.
• Designed for single-supply operation with no phase reversal upon overdrive.
• Provides high open-loop gain and low distortion suitable for AC applications.

Applications

• Current sensing
• Barcode scanners
• PA controls
• Battery-powered instrumentation
• Multipole filters

Procurement Notes

Verify the specific grade (A or D) required for your application, as offset voltage specifications differ significantly between them. Confirm that the SOT-23-5 package dimensions align with your PCB footprint constraints. Ensure the operating temperature range of -40°C to +125°C meets your environmental requirements. Check for automotive qualification if applicable to your design standards.

Selection Notes

Select this component when high DC precision is needed alongside wide signal bandwidth in a compact surface-mount package. It is suitable for buffering CMOS ADCs and DACs due to its rail-to-rail characteristics. Consider the A Grade for tighter offset voltage tolerances or the D Grade for cost-sensitive applications with relaxed DC precision requirements.

Part Context

This part belongs to the AD860x family, which includes dual (AD8602) and quad (AD8604) variants. All members share similar performance characteristics but differ in channel count and package options. The AD8601 specifically offers a single amplifier in a tiny 5-lead SOT-23 package, making it ideal for space-constrained portable devices.

Replacement Considerations

Direct functional substitutes within the same family include the AD8602ARZ and AD8604ARZ, though these offer multiple channels and different pinouts. Other single-channel precision amplifiers may require circuit redesign due to differences in pin configuration or electrical specifications.
