AD8613AUJZ-REEL

Overview

The AD8613AUJZ-REEL is a single-channel, low-cost micropower CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates from a single supply of 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.5 V. Key electrical specifications include a maximum offset voltage of 2.2 mV, a maximum input bias current of 1 pA, and a typical supply current of 38 μA per amplifier. The device offers a gain-bandwidth product of 350 kHz to 400 kHz, a slew rate of 0.1 V/μs, and an input voltage noise density of 22 nV/√Hz at 10 kHz. It is housed in a 5-lead TSOT-23 package.

Feature Summary

• Rail-to-rail input and output operation enables full signal swing in low-voltage single-supply systems.
• Micropower consumption with a maximum supply current of 50 μA per amplifier across the operating temperature range.
• Low noise performance with an input voltage noise density of 22 nV/√Hz at 10 kHz.
• No phase reversal occurs when the common-mode voltage approaches the negative supply rail.

Applications

• Battery-powered instrumentation
• Multipole filters
• Current shunt sense circuits
• ADC predrivers and DAC drivers
• Low power ASIC input or output amplifiers

Procurement Notes

Verify that the component matches the specific 5-lead TSOT-23 (UJ) package configuration required for the design. Confirm RoHS compliance status as indicated by the Z suffix in the ordering guide. Ensure the reel packaging format aligns with automated assembly equipment specifications before finalizing procurement orders.

Selection Notes

Select this component for applications requiring low power consumption combined with precision DC characteristics. The rail-to-rail I/O functionality makes it suitable for buffering CMOS ADCs and DACs where maximizing dynamic range is critical. Consider the 1 pA maximum input bias current for high-impedance sensor interfaces.

Part Context

This part belongs to the AD8613/AD8617/AD8619 family of low-cost micropower, low-noise CMOS rail-to-rail input/output operational amplifiers manufactured by Analog Devices Inc. The family includes single, dual, and quad channel variants designed for portable and loop-powered instrumentation applications.

Replacement Considerations

The AD8613AKSZ-REEL7 serves as a direct functional replacement, offering identical electrical specifications but utilizing a 5-lead SC70 package instead of the TSOT-23 form factor.
