AD8611ARZ-REEL

Overview

The AD8611ARZ-REEL is a single-channel ultrafast comparator manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 3 V to 5 V and features a propagation delay of 4 ns at 5 V, with a maximum of 5.5 ns. The device includes a latch function that is functional only when the supply voltage exceeds 4.3 V. It utilizes complementary outputs and supports an input frequency up to 100 MHz. The component is housed in an 8-lead narrow body SOIC package and is rated for operation within an industrial temperature range of -40°C to +85°C.

Feature Summary

• Features a 4 ns propagation delay suitable for high-speed timing circuits
• Includes a latch function to maintain constant output states
• Provides complementary digital outputs
• Supports single-supply operation between 3 V and 5 V

Applications

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

Procurement Notes

Verify the specific ordering suffix REEL against manufacturer documentation to confirm reel packaging specifications. Ensure the selected variant matches the required 8-lead SOIC package dimensions. Confirm compliance with RoHS directives as indicated in official datasheets. Validate that the supply voltage requirements align with system constraints before integration.

Selection Notes

Select this component for applications requiring fast response times and low power consumption. The AD8611 offers improved propagation delay compared to LT1394 and LT1016 designs. Consider the latch functionality if data retention during signal transitions is necessary. Ensure source impedance remains below 1 kΩ to optimize performance and minimize propagation delay variations.

Part Context

The AD8611 is part of the AD8611/AD8612 family of ultrafast comparators. While the AD8612 provides dual channels in a 14-lead TSSOP package, the AD8611ARZ-REEL specifically denotes the single-channel version in an 8-lead SOIC package. This series is designed to replace older comparator models with enhanced speed and lower current draw.

Replacement Considerations

The AD8611 is pin-for-pin compatible with the LT1016 and LT1394. When replacing these devices, account for differences in input common-mode voltage range, input bias current direction, and output voltage swing. Verify that the system can accommodate the lower supply current and faster propagation delay characteristics.
