AD8613AUJZ-REEL7

Overview

The AD8613AUJZ-REEL7 is a single-channel, low-cost, micropower CMOS operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 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 voltage noise density of 22 nV/√Hz at 10 kHz. The device draws a typical supply current of 38 µA per amplifier and offers a gain-bandwidth product of 400 kHz. It is housed in a 5-lead TSOT-23 package.

Feature Summary

• Rail-to-rail input and output operation without phase reversal
• Micropower consumption with very low input bias current
• Low noise performance suitable for precision signal conditioning
• Unity gain stable design

Applications

• Battery-powered instrumentation
• Multipole filters
• Current shunt sense circuits
• ADC predrivers
• DAC drivers and level shifters

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the reel packaging format required for your assembly line. Confirm that the UJ-5 package option matches your PCB footprint requirements. Ensure the component meets RoHS compliance standards if mandated by your manufacturing regulations. Cross-reference the manufacturer part number with official distributor catalogs to validate authenticity and availability status before finalizing procurement orders.

Selection Notes

Select this component when designing portable systems requiring low power consumption alongside high precision. The rail-to-rail I/O capability makes it ideal for buffering CMOS ADCs and DACs in low-voltage environments. Consider the 1 pA input bias current for applications involving high-impedance sensors. Verify that the 2.2 mV maximum offset voltage meets the accuracy requirements of your specific signal chain.

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 AD8613 variant specifically provides a single amplifier channel, whereas other family members offer dual or quad configurations. The AUJZ suffix indicates the 5-lead TSOT-23 package type.

Replacement Considerations

Direct substitutes within the same family include AD8613AKSZ variants for SC70 packaging. For automotive applications, consider the AD8617W or AD8619W models which are qualified for such environments.
