AD8611AR-REEL7

Overview

The AD8611AR-REEL7 is a single-channel ultrafast comparator from Analog Devices, featuring a 4 ns propagation delay at 5 V and complementary outputs. It operates on a single supply of 3 V to 5 V with an input frequency capability of 100 MHz. The device includes a latch function that requires VCC greater than 4.3 V for proper operation. It offers a wide common-mode input range extending to the negative rail and closely matched rising/falling delays for accurate clock recovery.

Feature Summary

• Ultrafast 4 ns propagation delay suitable for high-speed timing circuits
• Integrated latch function maintains output state independent of input changes
• Complementary digital outputs provide both true and inverted signals
• Wide common-mode input range extends down to the negative supply rail

Applications

• High speed timing circuits
• Clock recovery and distribution systems
• Line receivers in digital communications
• Phase detectors and zero-crossing detection
• High speed analog-to-digital converter (ADC) read channels

Procurement Notes

Verify the specific REEL7 suffix indicates tape-and-reel packaging when sourcing. Confirm the component meets RoHS3 compliance standards required by your assembly process. Ensure the ordering part number matches the exact package variant needed for your PCB footprint design.

Selection Notes

Select this component for applications requiring sub-5 ns response times and precise duty cycle preservation. The pinout is compatible with LT1016 and LT1394 designs but offers lower power consumption. Verify that the system supply voltage exceeds 4.3 V if the internal latch functionality is required for signal retention.

Part Context

This part belongs to the AD8611/AD8612 family of ultrafast comparators manufactured by Analog Devices. The AD8611 represents the single-channel version, while the AD8612 provides dual channels. Both share identical electrical characteristics and are designed for industrial temperature ranges.

Replacement Considerations

The AD8611 is pin-for-pin compatible with the LT1016 and LT1394. When replacing these legacy parts, account for differences in input bias current direction and common-mode voltage range limits.
