AD8601WARTZ-RL

Overview

The AD8601WARTZ-RL 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 5 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 per amplifier. Key electrical characteristics include a maximum offset voltage of 500 µV (A Grade) and an input bias current of 200 pA. It is housed in a 5-lead SOT-23 package and qualified for automotive applications under AEC-Q100 standards.

Feature Summary

• Utilizes patented DigiTrim technology to achieve superior DC precision without laser trimming.
• Features true rail-to-rail input and output stages maximizing signal swing in single-supply systems.
• Designed for low power consumption with minimal supply current requirements.
• Includes input overvoltage protection and exhibits no phase reversal during overload conditions.

Applications

• Current sensing circuits
• Barcode scanners
• Power Amplifier (PA) controls
• Battery-powered instrumentation
• Multipole filters

Procurement Notes

Verify the specific grade (A or D) required for your application, as offset voltage specifications vary significantly between them. Confirm that the WARTZ suffix corresponds to the correct automotive qualification and packaging format for your manufacturing process. Ensure compatibility with the 5-lead SOT-23 footprint during PCB layout. Check for any recent lifecycle status changes or alternative package options if long-term supply assurance is critical.

Selection Notes

Select this component when high precision and wide bandwidth are needed in a compact surface-mount package. The rail-to-rail I/O makes it suitable for buffering ADCs and DACs in low-voltage single-supply designs. Consider the A Grade for tighter offset voltage tolerances or the D Grade for cost-sensitive applications with relaxed DC precision. Evaluate thermal resistance values if operating near the upper temperature limits.

Part Context

This part belongs to the AD860x family of precision amplifiers, which includes dual (AD8602) and quad (AD8604) variants. The family shares common architectural features such as CMOS rail-to-rail inputs and outputs, low noise performance, and DigiTrim calibration technology. All variants are designed for similar single-supply applications but differ in channel count and package configurations to suit different integration densities.

Replacement Considerations

Direct functional replacements within the same family include AD8601ARTZ-REEL7 and AD8601WARTZ-R7. Verify pinout compatibility and ensure the substitute meets the specific AEC-Q100 automotive qualification if required by the design.
