ADCMP608BKSZ-RL

Overview

The ADCMP608BKSZ-RL is a fast, low-power comparator fabricated on Analog Devices' proprietary XFCB2 process. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features rail-to-rail input capability with a common-mode range extending from −0.2 V to VCC + 0.2 V. The device provides a TTL/CMOS-compatible output stage capable of driving up to 15 pF load capacitance while maintaining rated timing specifications. Key electrical parameters include a typical propagation delay of 40 ns at 10 mV overdrive, a typical supply current of 500 µA, and a power dissipation of 1 mW at 2.5 V. It includes a shutdown pin for power management and offers robust protection against large signal overdrive without phase reversal.

Procurement Notes

Verify the specific ordering suffix (RL) corresponds to the reel packaging configuration required for your assembly line. Confirm that the component meets RoHS compliance standards as indicated by the Z suffix in the base model number. Ensure the selected package variant matches the footprint requirements of your PCB design. Cross-reference the manufacturer's latest documentation for any potential product change notifications or lifecycle status updates before finalizing procurement plans.

Selection Notes

Select this component when designing circuits requiring fast response times with minimal power consumption under single-supply conditions. The wide operating temperature range supports deployment in demanding industrial environments. Consider the 6-lead SC70 package constraints regarding thermal resistance and physical space limitations. Evaluate the need for external buffering if the application demands driving loads exceeding the specified capacitive limits to maintain optimal performance.
