AD85610003RUR

Specialized ICS Overview

The AD85610003RUR is a single ultrafast comparator from Analog Devices, part of the AD8561 series. It features a typical propagation delay of 7 ns at 5 V and operates on a single supply voltage ranging from 3 V to 10 V. The device includes a latch function and offers complementary digital outputs capable of sourcing or sinking up to 3.2 mA. Input characteristics include a maximum offset voltage of 7 mV and an input bias current of -6 µA. It is specified for industrial temperatures between –40°C and +85°C.

Specialized ICS Feature Summary

• Ultrafast 7 ns propagation delay with closely matched rising and falling signal delays.
• Single supply operation from 3 V to 10 V with low power consumption (typical 5.5 mA).
• Integrated latch function for data retention at the output.
• Complementary digital outputs with high drive capability.

Specialized ICS Applications

• High speed timing circuits
• Clock recovery and clock distribution
• Line receivers
• Digital communications
• Phase detectors

Specialized ICS Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and reel specifications. Ensure compatibility with existing PCB footprints, as the component is available in multiple surface-mount packages including TSSOP-8 and SOIC-8. Confirm RoHS compliance status if required by project standards.

Specialized ICS Selection Notes

Select this component for applications requiring fast response times and low power consumption. The wide common-mode input range allows operation from the negative rail to within 2.2 V of the positive rail. Consider the latch feature if data retention is necessary without external circuitry. Ensure source impedance is kept below 1 kΩ to maintain optimal high-speed performance.

Specialized ICS Part Context

The AD8561 serves as a direct pin-compatible upgrade for the LT1016 comparator, offering lower supply current and a wider common-mode input range. It is designed to replace legacy comparators in high-speed designs while providing improved performance metrics such as faster propagation delay and reduced power consumption across the industrial temperature range.

Specialized ICS Replacement Considerations

The AD8561 is pin-compatible with the LT1016. When replacing, account for differences in input voltage range, bias current direction, and output swing. Verify that the system timing accommodates the faster propagation delay of the AD8561 compared to the LT1016.

Specialized ICS FAQ

What is the input common-mode voltage range?

The input common-mode voltage range extends from the negative supply rail to within 2.2 V of the positive supply rail.

How does the latch function operate?

When the latch input goes high, the output remains constant regardless of input voltages. A logic high requires a minimum of +2.0 V, and a logic low requires a maximum of +0.8 V.

What are the setup and hold times for the latch?

The setup time is approximately 2 ns to 3 ns, and the hold time is 3 ns. New output data appears in approximately 8 ns after the latch input goes low.
