ADCMP600BKSZ-R2

Overview

The ADCMP600BKSZ-R2 is a single-channel, rail-to-rail analog comparator from Analog Devices Inc., housed in a 5-lead SC-70 surface-mount package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical supply current of 4 mA. The device features a TTL/CMOS-compatible output stage capable of driving up to 50 mA per channel. Key electrical specifications include a propagation delay of 3.5 ns at 2.5 V and 5 ns at 10 mV overdrive, an input offset voltage of ±5 mV, and a common-mode rejection ratio of 50 dB. It supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Rail-to-rail input and output capability allowing operation across the full supply voltage range.
• TTL- and CMOS-compatible output stage designed for direct logic interfacing.
• Fixed internal hysteresis mechanism to improve noise immunity.
• Robust input protection against large overdrive voltages without phase reversal.

Applications

• High-speed instrumentation systems
• Clock and data signal restoration circuits
• Logic level shifting or translation applications
• Threshold detection and peak detectors
• Pulse-width modulators and trigger circuitry

Procurement Notes

Verify the specific suffix R2 indicates reel packaging when sourcing. Confirm the SC-70-5 package variant matches the design footprint. Ensure the component meets RoHS compliance requirements for the target assembly process. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components. Check for any specific handling precautions related to electrostatic discharge during installation.

Selection Notes

Select this component for applications requiring fast response times within a low-voltage single-supply environment. The fixed hysteresis suits designs needing basic noise filtering without external resistor networks. Consider the SC-70 package size for space-constrained PCB layouts. Evaluate the 50 mA output drive capability against the load requirements. Verify that the 3.5 ns propagation delay meets the system timing constraints.

Part Context

This device belongs to the ADCMP600/ADCMP601/ADCMP602 family of very fast comparators fabricated on Analog Devices' proprietary XFCB2 process. While the ADCMP601 adds a latch/hysteresis control pin and the ADCMP602 includes a shutdown feature, the ADCMP600 provides a simplified general-purpose solution. It serves as an improved replacement for older high-speed comparator models like the MAX999.

Replacement Considerations

The datasheet identifies the ADCMP600 series as an improved replacement for the Maxim MAX999 comparator. Engineers transitioning from the MAX999 should verify pin compatibility and electrical parameter alignment. No other specific substitute part numbers are documented in the provided source material.
