ADCMP601BKSZ-R2

Overview

The ADCMP601BKSZ-R2 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 propagation delay of 3.5 ns and a typical supply current of 4 mA. It includes a latch enable/hysteresis control pin for programmable hysteresis adjustment or latching functionality. The output stage provides TTL/CMOS compatibility with an output current capability of 50 mA. It is housed in a 6-lead SC-70 package.

Feature Summary

• Features a low glitch CMOS/TTL-compatible output stage capable of driving up to 5 pF load capacitance.
• Includes a dedicated LE/HYS pin allowing for programmable hysteresis adjustment via external resistor or current source, or operation as a high-speed latch.
• Supports split input/output supplies without sequencing restrictions, enabling independent output swing control and power savings.
• Offers robust protection against large input overdrive with no phase reversal when the valid input signal range is 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 R2 indicates reel packaging configuration. Confirm the component matches the 6-lead SC-70 outline dimensions provided in the datasheet. Ensure the operating temperature range aligns with system requirements. Check for RoHS compliance status if required by manufacturing standards. Validate that the single-supply voltage range meets circuit design constraints.

Selection Notes

Select this component for applications requiring fast response times and precise threshold detection. The integrated latch feature simplifies circuit design for pulse holding applications. Consider the low propagation delay dispersion for time-critical systems. Evaluate the programmable hysteresis capability to mitigate noise in sensitive environments. Ensure the SC-70 package size fits the available PCB real estate.

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 lacks the latch/hysteresis pin and the ADCMP2 adds a shutdown pin, the ADCMP601 specifically integrates the LE/HYS control functionality within the 6-lead SC-70 package.

Replacement Considerations

The datasheet identifies the MAX999 as an improved replacement target. Verify pinout compatibility and electrical specifications before substituting with other single-channel comparators. Ensure any alternative supports the required 3.5 ns propagation delay and latch functionality.

FAQ

How is the hysteresis value adjusted?

Hysteresis is controlled via the LE/HYS pin by biasing it with an external resistor or current source. Connecting the pin to VCC removes hysteresis, while leaving it disconnected results in a fixed hysteresis of approximately 2 mV.

Can the input and output supplies be separated?

Yes, the device supports split input/output supplies (VCCI and VCCO) without sequencing restrictions, allowing for independent output swing control.
