AD8611ARMZ-REEL

Overview

The AD8611ARMZ-REEL is a single-channel ultrafast comparator from Analog Devices, housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 3 V to 5 V. The device features a typical propagation delay of 4 ns at 5 V and supports input frequencies up to 100 MHz. It includes a latch function that requires VCC greater than 4.3 V for operation. Key electrical specifications include a maximum offset voltage of 7 mV, a common-mode rejection ratio of 85 dB, and a maximum supply current of 10 mA per channel.

Feature Summary

• Features complementary digital outputs with integrated latch functionality for data retention.
• Provides closely matched rising and falling propagation delays across the operating temperature range.
• Supports a wide common-mode input voltage range extending to the negative supply rail.

Applications

• High speed timing circuits
• Clock recovery and clock distribution systems
• Line receivers
• Digital communications phase detectors
• High speed analog-to-digital converter (ADC) interfaces

Procurement Notes

Verify the specific ordering suffix REEL against the manufacturer's official documentation to confirm tape-and-reel packaging configuration. Ensure the component matches the 8-lead MSOP physical footprint and pinout requirements for the target PCB layout. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement orders.

Selection Notes

Select this component when system design requires sub-5 ns propagation delay and single-supply operation between 3 V and 5 V. The integrated latch feature is suitable for applications requiring output state retention independent of subsequent input changes. Verify that the supply voltage remains above 4.3 V if the latch functionality is required for the specific application logic.

Part Context

This part belongs to the AD8611/AD8612 family of ultrafast comparators manufactured by Analog Devices. The AD8611 represents the single-channel variant, while the AD8612 provides dual channels. Both variants share identical electrical characteristics and are designed as high-performance replacements for legacy LT1016 and LT1394 designs.

Replacement Considerations

The AD8611 offers pin-for-pin compatibility with the LT1016 and LT1394. When replacing these devices, account for differences in input bias current direction and wider common-mode input range. Verify that the improved propagation delay and lower power consumption align with the existing circuit performance requirements.
