Overview
The AD8561ARZ-REEL is an ultrafast single-supply comparator from Analog Devices, packaged in an 8-lead narrow SOIC (R-8) reel. It features a typical propagation delay of 7 ns at 5 V supply voltage and operates on a single supply ranging from 3 V to 10 V. The device includes a latch function with a typical enable pulse width of 6 ns. It supports industrial temperature operation from –40°C to +85°C and offers complementary digital outputs.
Feature Summary
- Ultrafast 7 ns propagation delay suitable for high-speed timing applications
- Integrated latch function for data retention at the output
- Compatible pinout with LT1016 designs while offering lower power consumption
- Complementary digital output configuration
Applications
- High Speed Timing
- Clock Recovery and Clock Distribution
- Line Receivers
- Digital Communications
- Phase Detectors
Procurement Notes
Verify that the specific part number matches the required package style and reel quantity. Confirm RoHS compliance status if mandated by project specifications. Ensure proper electrostatic discharge precautions are implemented during handling and assembly to prevent damage to the sensitive internal circuitry.
Selection Notes
Select this component when a fast response time is critical for signal processing tasks. The wide common-mode input range extending to the negative rail allows flexibility in signal interfacing. Consider the low power consumption relative to legacy comparators like the LT1016 for battery-operated or thermally constrained systems.
Part Context
This device belongs to the AD8561 family of ultrafast comparators manufactured by Analog Devices. It serves as a direct upgrade for LT1016 designs, providing improved speed and reduced current draw. The family is available in multiple packages including plastic DIP, TSSOP, and narrow SOIC to accommodate various board layout requirements.
Replacement Considerations
The AD8561 is pin-compatible with the LT1016. When replacing LT1016 designs, account for differences in input voltage range, bias current direction, and output swing characteristics to ensure proper circuit operation.
