ADCMP601BKSZ-RL

Overview

The ADCMP601BKSZ-RL is a single-channel, rail-to-rail analog comparator from Analog Devices. It operates on a single supply voltage ranging from 2.5 V to 5.5 V. The device features a TTL/CMOS-compatible output stage and offers a propagation delay of 3.5 ns at 2.5 V and 4.3 ns at 5.5 V with a 50 mV overdrive. Typical supply current is 3 mA at 2.5 V and 3.5 mA at 5.5 V. Input offset voltage is typically ±2 mV, with a maximum of ±5 mV. It includes a LE/HYS pin for programmable hysteresis or latch control. The component is housed in a 6-lead SC-70 package.

Feature Summary

• Features a low glitch CMOS/TTL-compatible output stage designed to drive capacitive loads gracefully.
• Includes a dedicated LE/HYS pin allowing for programmable hysteresis adjustment or high-speed latch functionality via a single control interface.
• Supports split input/output supplies without sequencing restrictions, enabling independent output swing control and power optimization.
• Provides robust protection against large input overdrive signals and prevents phase reversal when valid input ranges are exceeded.

Applications

• High speed instrumentation
• Clock and data signal restoration
• Logic level shifting or translation
• Pulse spectroscopy
• Automatic test equipment (ATE)

Procurement Notes

Verify the specific suffix 'RL' indicates reel packaging configuration. Confirm the lead-free status and RoHS compliance details through official manufacturer documentation. Ensure the SC-70-6 footprint matches the target PCB design. Check for any obsolescence notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component for applications requiring fast response times and precise threshold detection within a single-supply environment. The integrated latch and hysteresis controls reduce external component count compared to standard comparators. Consider the 3.5 ns propagation delay for high-frequency signal processing tasks. Evaluate the 2.5 V to 5.5 V operating range against system power constraints.

Part Context

This part belongs to the ADCMP600/ADCMP601/ADCMP602 family of very fast comparators fabricated on Analog Devices' proprietary XFCB2 process. The ADCMP601 variant specifically provides a single channel with latch/hysteresis capabilities in a compact 6-lead SC-70 package, distinguishing it from the ADCMP600 (no latch) and ADCMP602 (shutdown pin).

Replacement Considerations

The datasheet identifies the MAX999 as an improved replacement target. Verify electrical compatibility regarding propagation delay and supply voltage ranges when substituting other single-channel comparators.
