AD8611ARM-R2

Overview

The AD8611ARM-R2 is a single ultrafast comparator from Analog Devices, housed in an 8-lead MSOP package. It operates on a single supply between 3 V and 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 for maintaining output states and provides complementary outputs. The input common-mode range extends to the negative supply rail.

Feature Summary

• Ultrafast response with 4 ns propagation delay for high-speed timing applications
• Integrated latch function to maintain constant output states independent of input changes
• Complementary digital outputs for flexible logic interfacing
• Single-supply operation compatible with standard voltage rails

Applications

• High speed timing circuits
• Clock recovery and distribution systems
• Line receivers and digital communications
• Phase detectors and zero-crossing detection
• Read channel detection in PCMCIA cards

Procurement Notes

Verify the specific ordering suffix R2 corresponds to the required tape and reel quantity configuration. Confirm the MSOP package variant matches the PCB footprint requirements. Ensure the component meets all environmental specifications for the intended operating temperature range before finalizing procurement.

Selection Notes

Select this component when a fast response time and integrated latching capability are required in a compact surface-mount package. It serves as a direct pin-compatible upgrade for LT1394 and LT1016 designs, offering lower power consumption and improved propagation delay characteristics while maintaining similar functionality.

Part Context

This part belongs to the AD8611/AD8612 family of ultrafast comparators. The AD8611 represents the single-channel version, while the AD8612 offers dual channels. Both share identical electrical specifications and are designed for high-speed signal processing applications requiring precise timing and low latency.

Replacement Considerations

The AD8611 is pin-for-pin compatible with the LT1394 and LT1016. When replacing these legacy parts, verify that the input common-mode voltage range and bias current directions align with the existing circuit design to ensure proper operation.
