ADCMP601BKSZ-REEL7

Overview

The ADCMP601BKSZ-REEL7 is a single-channel, rail-to-rail analog comparator manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.5 V to 5.5 V and features a propagation delay of 3.5 ns at 2.5 V with a 50 mV overdrive. The device consumes 4 mA of supply current and offers an input common-mode range extending from −0.2 V to VCC + 0.2 V. It includes a latch/hysteresis control pin (LE/HYS) for programmable hysteresis or latching functionality. The component is housed in a 6-lead SC-70 package and supports operation across a temperature range of −40°C to +125°C.

Feature Summary

• Features a low glitch CMOS/TTL-compatible output stage capable of driving capacitive loads gracefully.
• Includes a dedicated LE/HYS pin allowing for programmable hysteresis adjustment or high-speed latch mode activation via a single control interface.
• Provides robust input protection against large overdrive conditions without causing output phase reversal.
• Delivers high power supply rejection ratio exceeding 50 dB to maintain performance under varying supply conditions.

Applications

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

Procurement Notes

Verify the specific suffix REEL7 indicates reel packaging when sourcing components. Confirm that the lead-free status aligns with RoHS requirements for your assembly process. Ensure the SC-70-6 footprint matches your PCB design constraints. Check for any obsolescence notices or lifecycle status updates directly from Analog Devices before finalizing procurement plans.

Selection Notes

Select this component when a single-channel comparator with integrated latch capability is required. The shared VCCI/VCCO pin simplifies single-supply designs compared to split-supply variants like the ADCMP602. Consider the 3.5 ns propagation delay and 4 mA current consumption for power-sensitive high-speed applications. Verify that the 6-lead SC-70 package fits within the available board space.

Part Context

This part belongs to the ADCMP600/ADCMP601/ADCMP602 family of very fast comparators fabricated on Analog Devices' proprietary XFCB2 process. While the ADCMP600 offers five leads and the ADCMP602 provides eight leads with separate input/output supplies and a shutdown pin, the ADCMP601 specifically integrates the latch/hysteresis control into a compact six-lead SC-70 package.

Replacement Considerations

The datasheet identifies this series as an improved replacement for the MAX999. Engineers transitioning from the MAX999 should verify pin compatibility and ensure that the latch/hysteresis control functions are properly configured in the new design.

FAQ

How is the latch function activated on the ADCMP601?

The latch function is activated by driving the LE/HYS pin low. When this pin is driven low, the comparator enters latch mode, holding the output state based on the input condition at the time of the latch enable transition.

What is the purpose of the LE/HYS pin if not used for latching?

If not used for latching, the LE/HYS pin can be biased with a resistor or current source to set programmable hysteresis. Connecting an external pull-down resistor varies the hysteresis amount predictably, improving stability in noisy environments.
