ADCMP609BRMZ

Overview

The ADCMPMP609BRMZ is a rail-to-rail, fast, low-power single-supply comparator operating from 2.5 V to 5.5 V. It features TTL/CMOS-compatible outputs, a shutdown pin, and programmable hysteresis. Key electrical parameters include a typical propagation delay of 40 ns at 1 mW power dissipation (2.5 V supply), input common-mode range extending from −0.2 V to VCC + 0.2 V, and supply rejection greater than 60 dB. The device operates within an ambient temperature range of −40°C to +125°C and is housed in an 8-lead MSOP package.

Feature Summary

• Rail-to-rail input capability with extended common-mode voltage range beyond supply rails.
• TTL- and CMOS-compatible output stage designed for direct driving of logic loads.
• Integrated shutdown pin for power management and programmable hysteresis control via external resistor.

Applications

• High speed instrumentation
• Clock and data signal restoration
• Logic level shifting or translation
• Threshold detection
• Peak and zero-crossing detectors

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as reel or tape-and-reel quantities, as indicated in the manufacturer's ordering guide. Confirm that the RoHS compliant designation aligns with environmental regulations for your target market. Ensure the thermal resistance characteristics are suitable for your PCB layout to maintain junction temperatures within absolute maximum ratings during operation.

Selection Notes

Select this component when rail-to-rail input compatibility is required alongside low power consumption in single-supply systems. The integrated shutdown feature makes it suitable for battery-operated applications requiring power management. Consider the programmable hysteresis for noisy environments where stable switching thresholds are critical without adding external feedback networks.

Part Context

This part belongs to Analog Devices' family of high-speed comparators fabricated on proprietary XFCB2 process technology. It shares functional similarities with other models in the series but is distinguished by its specific combination of low power, rail-to-rail inputs, and integrated hysteresis control. The 8-lead MSOP package provides a compact solution for space-constrained designs.

Replacement Considerations

Direct substitutes may include other parts from the ADCMP60x series, such as the ADCMP608, if pin compatibility and performance specifications align with the application requirements. Verify that any replacement maintains the same supply voltage range and output drive capabilities.

FAQ

How is hysteresis programmed on the ADCMP609?

Hysteresis is controlled via the HYS pin by connecting an external pull-down resistor or current source to ground. Leaving the pin disconnected removes hysteresis.

What is the input common-mode voltage range?

The input common-mode voltage ranges from −0.2 V to VCC + 0.2 V, allowing full rail-to-rail operation.
