ADCMP602BRMZ-REEL

Overview

The ADCMP602BRMZ-REEL is a single-channel, very fast comparator from Analog Devices, housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V. The device features rail-to-rail input common-mode voltage capability from −0.2 V to VCC + 0.2 V and a low-glitch CMOS/TTL-compatible output stage capable of driving up to 50 mA. Key electrical specifications include a typical propagation delay of 3.5 ns at 50 mV overdrive, a maximum offset voltage of ±5.0 mV, and a typical bias current of ±2 µA. It includes dedicated pins for shutdown control and latch/hysteresis adjustment.

Feature Summary

• Features a dedicated shutdown pin (SDN) for power management and a latch enable/hysteresis control pin (LE/HYS) for programmable hysteresis or high-speed latching via a single-pin interface.
• Provides rail-to-rail input operation with robust protection against large input overdrive, ensuring outputs do not phase reverse when valid input signal ranges are exceeded.
• Delivers a low-glitch, TTL/CMOS-compatible output stage designed to drive capacitive loads gracefully while maintaining specified timing performance.

Applications

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

Procurement Notes

Verify the REEL suffix indicates tape-and-reel packaging suitable for automated assembly processes. Confirm the specific revision (Rev. A) matches design requirements. Ensure ESD precautions are observed during handling, as the device is sensitive to electrostatic discharge. Cross-reference the 8-lead MSOP outline dimensions with PCB footprint libraries to guarantee mechanical compatibility before finalizing procurement orders.

Selection Notes

Select this component when a single-supply, high-speed comparator with integrated latch and shutdown functionality is required. It serves as an improved replacement for older models like the MAX999. Consider the split supply capability (VCCI and VCCO) if independent output swing control or power savings are needed. Verify that the 3.5 ns propagation delay meets system timing constraints and that the 8-lead MSOP package fits the available board space.

Part Context

This part belongs to the ADCMP600/ADCMP601/ADCMP602 family of rail-to-rail comparators fabricated on Analog Devices' proprietary XFCB2 process. While the ADCMP600 and ADCMP601 offer fewer pins and lack the shutdown feature, the ADCMP602 provides enhanced versatility through its additional control pins. The family is designed for applications requiring low noise and high speed within a compact surface-mount form factor.

Replacement Considerations

The datasheet explicitly identifies the ADCMP602 as an improved replacement for the MAX999. When substituting, verify that the target application can accommodate the specific pinout differences and the inclusion of the SDN and LE/HYS pins found on the ADCMP602 but absent in simpler comparator variants.
