ADCMP609BRMZ-REEL

Overview

The ADCMP609BRMZ-REEL is a single-channel, rail-to-rail analog comparator from Analog Devices Inc., housed in an 8-lead MSOP package. It operates on a single supply voltage ranging from 2.5 V to 5.5 V with a typical supply current of 500 µA at 2.5 V. The device features a TTL/CMOS-compatible output stage and supports input common-mode voltages from −0.2 V to VCC + 0.2 V. Key electrical specifications include a propagation delay of 40 ns, an offset voltage of ±3 mV, and a shutdown pin for power management.

Feature Summary

• Features a fully specified rail-to-rail input range extending beyond the supply rails.
• Includes a dedicated shutdown pin to reduce power consumption during idle periods.
• Offers programmable hysteresis via an external resistor connected to the HYS pin.
• Provides low-glitch, TTL/CMOS-compatible outputs capable of driving standard logic loads.

Applications

• High speed instrumentation
• Clock and data signal restoration
• Logic level shifting or translation
• Threshold detection
• Pulse-width modulators

Procurement Notes

Verify the specific ordering suffix matches the required packaging format, as the REEL designation indicates tape-and-reel delivery. Confirm that the RoHS compliant status aligns with regulatory requirements for the target assembly process. Ensure the operating temperature range of −40°C to +125°C meets the environmental constraints of the final application before procurement.

Selection Notes

Select this component when a fast, low-power comparator with rail-to-rail inputs is required. The device is suitable for applications needing adjustable hysteresis to prevent noise-induced switching. Consider the 40 ns propagation delay and 500 µA supply current for timing-critical and battery-operated designs. Verify that the 8-lead MSOP package fits the available PCB real estate.

Part Context

This part belongs to the ADCMP609 series of high-speed comparators manufactured by Analog Devices Inc. The series utilizes XFCB2 proprietary process technology to achieve fast response times while maintaining low power consumption. The BRMZ variant specifically denotes the industrial temperature range and RoHS compliance within the broader product family.

Replacement Considerations

Direct substitutes within the same package and specification profile should be verified against the official Analog Devices cross-reference guide. Ensure any replacement maintains the 2.5 V to 5.5 V supply range and rail-to-rail input capability. Pin compatibility must be confirmed if substituting with other single-channel comparators.

FAQ

How is hysteresis programmed on the ADCMP609?

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

What is the function of the SDN pin?

The SDN (Shutdown) pin allows the user to place the device into a low-power sleep mode. Driving this pin low shuts down the comparator.

Can the ADCMP609 handle input signals exceeding the supply voltage?

Yes, the input common-mode voltage range extends from −0.2 V to VCC + 0.2 V, allowing it to handle signals slightly beyond the supply rails.
