ADCMP600BRJZ-REEL7

Overview

The ADCMP600BRJZ-REEL7 is a rail-to-rail, very fast single-supply comparator fabricated on Analog Devices' XFCB2 process. It operates within a supply voltage range of 2.5 V to 5.5 V and features an input common-mode voltage range from −0.2 V to VCC + 0.2 V. The device provides a low glitch CMOS/TTL-compatible output stage capable of driving up to 5 pF load capacitance. Key electrical specifications include a typical propagation delay of 3.5 ns at 2.5 V and power dissipation of 10 mW at 3.3 V. It offers a power supply rejection ratio exceeding 50 dB and fixed hysteresis of approximately 2 mV.

Feature Summary

• Features a low glitch CMOS/TTL-compatible output stage designed for high-speed digital interfacing.
• Includes robust input protection that prevents phase reversal when valid input signal ranges are exceeded.
• Provides high power supply rejection ratio (PSRR) exceeding 50 dB for improved noise immunity.
• Offers fixed hysteresis functionality to enhance stability in noisy environments.

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 package type matches the required PCB footprint, as the ADCMP600 series is available in SC70-5 and SOT-23-5 configurations. Confirm that the ordering suffix corresponds to the intended reel quantity and tape format. Ensure the component meets the required operating temperature range of −40°C to +125°C for the target application environment. Cross-reference the datasheet revision to confirm pinout consistency with existing designs.

Selection Notes

Select this comparator for applications requiring sub-nanosecond response times and low power consumption. The shared VCCI/VCCO pin simplifies single-supply designs, while the rail-to-rail input capability accommodates signals near ground and supply rails. Consider the ADCMP601 or ADCMP602 if programmable hysteresis or shutdown control is necessary, as the ADCMP600 provides only fixed hysteresis without these additional control pins.

Part Context

The ADCMP600 is part of a family of very fast comparators including the ADCMP601 and ADCMP602. It serves as an improved replacement for the MAX999 comparator. Manufactured using Analog Devices' proprietary XFCB2 process, it balances high speed with low power dissipation. The BRJZ suffix indicates a specific surface-mount package variant within the broader ADCMP600 product line.

Replacement Considerations

The datasheet identifies the ADCMP600 as an improved replacement for the MAX999. Verify pin compatibility and electrical parameter alignment before substitution. No other direct substitute part numbers are documented in the provided source material.
