AD8561AR-REEL

Overview

The AD8561AR-REEL is an ultrafast single-supply comparator from Analog Devices, packaged in an 8-lead TSSOP (RU-8) format. It features a typical propagation delay of 7 ns at 5 V and operates on a single supply voltage ranging from 3 V to 10 V. The device includes a low-power latch function with a typical pulse width of 6 ns. Electrical specifications include a maximum input offset voltage of 7 mV, a common-mode rejection ratio of 85 dB, and a large signal voltage gain of 3000 V/V. It supports complementary digital outputs and functions within an industrial temperature range of –40°C to +85°C.

Procurement Notes

Verify the specific package designation RU-8 corresponds to the 8-Lead Thin Shrink Small Outline Package when sourcing this reel variant. Confirm that the ordering suffix indicates tape-and-reel packaging suitable for automated assembly processes. Ensure the component meets RoHS compliance standards as indicated by manufacturer documentation. Cross-reference the part number against current distributor catalogs to validate availability status before finalizing procurement plans.

Selection Notes

Select this component for designs requiring fast response times and precise duty cycle matching due to closely matched rising and falling propagation delays. Consider its compatibility with LT1016 pinouts if upgrading existing circuits. Evaluate the wide common-mode input range extending to the negative rail for flexible signal interfacing. Assess power consumption requirements against the specified supply currents for battery-operated or low-power systems.

Part Context

The AD8561 series consists of ultrafast comparators designed for demanding high-speed applications. This specific model utilizes the TSSOP surface-mount package, offering space efficiency for modern circuit boards. It serves as a direct upgrade path for legacy LT1016 designs, providing improved speed and lower power consumption while maintaining pin compatibility.

Replacement Considerations

The AD8561 is explicitly documented as a pin-compatible replacement for the LT1016 comparator. Designers should account for differences in input voltage range, bias current direction, and output swing characteristics during the transition.
