AD8601ARTZ-REEL

Overview

The AD8601ARTZ-REEL is a single-channel, precision CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical supply current of 750 µA per amplifier. The device offers an 8 MHz gain bandwidth product and a slew rate of 5 V/µs at 3 V supplies. Key electrical characteristics include a maximum offset voltage of 500 µV (A Grade) and low input bias currents.

Feature Summary

• Utilizes patented DigiTrim technology for superior precision without laser trimming
• Features true rail-to-rail input and output stages for extended dynamic range
• Provides very low input bias currents suitable for high impedance sources
• Operates stably in unity-gain configurations

Applications

• Current sensing applications
• Barcode scanners
• Battery-powered instrumentation
• Multipole filters
• Audio amplification for portable devices

Procurement Notes

Verify the specific grade (A or D) required for your application, as offset voltage specifications vary significantly between grades. Confirm that the REEL suffix matches your automated assembly requirements. Ensure the operating temperature range aligns with your system's environmental conditions, as the device supports extended industrial temperatures.

Selection Notes

Select this component when single-supply operation and wide signal bandwidth are critical. The rail-to-rail architecture allows buffering of CMOS ADCs and DACs effectively. Consider the A Grade for strict DC precision requirements due to lower offset voltage limits compared to the D Grade. Evaluate thermal resistance values if operating near maximum junction temperatures.

Part Context

This part belongs to the AD8601/AD8602/AD8604 family of precision amplifiers manufactured by Analog Devices Inc. The AD8601 represents the single-channel variant within this series. It shares core architectural features with its dual and quad counterparts but is packaged specifically in a 5-lead SOT-23 format for space-constrained designs.

Replacement Considerations

Direct functional replacements within the same family include the AD8602 (dual channel) and AD8604 (quad channel), provided pin compatibility and channel count requirements are met. Verify package dimensions and pinout configurations when substituting.
