AD8613AKSZ-REEL7

Overview

The AD8613AKSZ-REEL7 is a single-channel, low-cost micropower operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities, allowing operation from a single supply of 1.8 V to 5.5 V or dual supplies of ±0.9 V to ±2.5 V. The device offers a maximum offset voltage of 2.2 mV and a maximum input bias current of 1 pA. It consumes a maximum supply current of 50 μA per amplifier over the operating temperature range. Key dynamic specifications include a gain-bandwidth product of 350 kHz to 400 kHz and a slew rate of 0.1 V/μs. The component operates within a temperature range of -40°C to +125°C and is housed in a 5-lead SC70 package.

Feature Summary

• Rail-to-rail input and output functionality enables full signal swing in low-voltage single-supply systems.
• Micropower consumption with a maximum supply current of 50 μA per amplifier supports battery-powered applications.
• Low noise performance with a voltage noise density of 25 nV/√Hz at 1 kHz.
• Unity gain stable design with no phase reversal upon overload.

Applications

• Battery-powered instrumentation
• Multipole filters
• Current shunt sense circuits
• Sensor signal conditioning
• ADC predriver stages

Procurement Notes

Verify the specific ordering suffix 'KS-5' corresponds to the 5-lead SC70 package variant required for your PCB layout. Confirm that the RoHS compliant status aligns with your manufacturing standards. Ensure the selected component meets the thermal resistance requirements for the intended enclosure environment. Cross-reference the datasheet revision H specifications against your system's absolute maximum ratings to prevent damage during operation.

Selection Notes

Select this component when designing portable or loop-powered instrumentation requiring low quiescent current and high precision. The rail-to-rail I/O capability makes it suitable for buffering CMOS ADCs and DACs where maximizing dynamic range is critical. Consider the 50 μA maximum supply current constraint for strict power budgeting scenarios. Verify that the 350 kHz gain-bandwidth product meets the bandwidth requirements of your specific filter or amplification topology.

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. The AD8613 specifically denotes the single-channel configuration available in compact packages such as the 5-lead SC70 and TSOT-23. This family is designed to provide high performance in space-constrained, low-power applications without compromising signal integrity.

Replacement Considerations

The AD8613AUJZ-REEL7 serves as a functional substitute within the same family, offering identical electrical characteristics but utilizing a 5-lead TSOT-23 package instead of the SC70 form factor. Designers must verify footprint compatibility when swapping between these package options.
