ADCMP609BRMZ-REEL7

Overview

The ADCMP609BRMZ-REEL7 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 includes dedicated shutdown and programmable hysteresis control pins. Key electrical specifications include a propagation delay of 40 ns, an input offset voltage of ±3 mV, and a power supply rejection ratio exceeding 60 dB.

Feature Summary

• Features a fully specified rail-to-rail input common-mode voltage range extending from −0.2 V to VCC + 0.2 V.
• Includes a dedicated shutdown pin for low-power sleep modes and a programmable hysteresis control pin for noise immunity.
• Provides a low-glitch, TTL/CMOS-compatible output stage capable of driving capacitive loads up to 15 pF.

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 REEL7 against the manufacturer's official documentation to confirm reel packaging specifications. Ensure the component matches the exact part number ADCMP609BRMZ-REEL7 for temperature range and RoHS compliance. Cross-reference datasheet revision C for accurate electrical characteristics before final procurement decisions.

Selection Notes

Select this component when a fast, low-power comparator with rail-to-rail inputs is required. The inclusion of a shutdown pin allows for significant power savings in battery-operated systems. The programmable hysteresis feature simplifies circuit design by eliminating the need for external feedback networks to prevent oscillation in noisy environments.

Part Context

This part belongs to the ADCMP609 series of high-speed comparators manufactured by Analog Devices Inc. It utilizes the proprietary XFCB2 process technology to achieve fast switching speeds while maintaining low power consumption. The device is designed for versatile applications requiring precise threshold detection and signal conditioning in compact surface-mount packages.

FAQ

How is hysteresis programmed on the ADCMP609?

Hysteresis is controlled via the HYS pin. Connecting an external pull-down resistor or a current source from the HYS pin to ground varies the amount of hysteresis predictably. Leaving the pin disconnected removes hysteresis.

What is the function of the SDN pin?

The SDN (Shutdown) pin allows the device to be placed into a low-power sleep mode. Driving this pin low shuts down the device, reducing the supply current significantly.
