AD8601ART-REEL7

Overview

The AD8601ART-REEL7 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. Key electrical characteristics include a maximum offset voltage of 500 µV (A Grade) and low input bias currents.

• Features true rail-to-rail input and output architecture allowing operation across the full supply voltage range.
• Designed for high-speed applications with wide signal bandwidth and low distortion characteristics.
• Includes input overvoltage protection and exhibits no phase reversal during overload conditions.

Applications

• Current sensing
• Barcode scanners
• Battery-powered instrumentation
• Multipole filters
• Audio amplification

Procurement Notes

Verify that the specific ordering suffix ARTZ corresponds to the intended package type and temperature grade. Confirm that the REEL7 designation matches the required tape and reel quantity for manufacturing integration. Ensure compatibility with the target PCB footprint and soldering profile requirements.

Selection Notes

Select this component when single-supply operation and rail-to-rail performance are required in a compact SOT-23 package. Consider the A Grade specifications if strict offset voltage limits are necessary. Evaluate the low input bias current suitability for high-impedance sensor interfaces or photodiode applications.

Part Context

This part belongs to the AD860x family of precision CMOS amplifiers manufactured by Analog Devices Inc. The family includes dual (AD8602) and quad (AD8604) variants sharing similar electrical characteristics. The AD8601 specifically provides a single amplifier solution optimized for space-constrained designs requiring high precision.

Replacement Considerations

Direct functional replacements within the same family include the AD8602 and AD8604, though pin counts differ. Verify package compatibility when substituting with other single-channel op-amps offering rail-to-rail I/O and similar bandwidth specifications.

FAQ

How does the AD8601 handle input overvoltage?

Excess input voltage energizes internal PN junctions, allowing current to flow to the supplies. Damage is prevented if the input current is limited to 5 mA or less, typically achieved using a series resistor.

What is the recovery time from overload conditions?

The output recovers from the positive supply rail within 200 ns at all supply voltages. Recovery from the negative rail is within 500 ns at a 5 V supply.
