MAX9075EXK+T

Overview

The MAX9075EXK+T is a single-channel analog comparator from the MAX9075/MAX9077 series, manufactured by Analog Devices Inc. (Maxim Integrated). It operates on a single supply voltage ranging from 2.1V to 5.5V and consumes only 3µA per comparator. The device features a propagation delay of 580ns and offers rail-to-rail push-pull outputs capable of driving loads up to 2mA. It utilizes a 5-pin SC-70 package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• Ultra-low power consumption with 3µA supply current per comparator
• Rail-to-rail push-pull output stage supporting TTL/CMOS logic interfaces
• Ground-sensing inputs allowing operation down to 0V common-mode voltage
• No differential clamp across inputs for extended input voltage range

Applications

• Battery-powered portable systems
• Threshold detectors and discriminators
• Keyless entry systems
• IR receivers
• Digital line receivers

Procurement Notes

Verify the component authenticity through official manufacturer channels or authorized distributors. Confirm the specific ordering suffix EXK+T corresponds to the 5-pin SC-70 package variant. Ensure compliance with RoHS standards as indicated by the plus sign in the part number. Check for lead-free soldering requirements during assembly processes.

Selection Notes

Select this comparator for applications requiring minimal power consumption in portable devices. The rail-to-rail input capability allows sensing signals near ground potential. The push-pull output eliminates the need for external pull-up resistors when interfacing with digital logic. Consider the 580ns propagation delay for timing-sensitive circuits.

Part Context

This component belongs to the MAX9075/MAX9077 family of low-cost, ultra-small comparators designed for single-supply operations. The MAX9075 represents the single-channel version, while the MAX9077 provides dual channels. Both share similar electrical characteristics but differ in pin count and package options to suit various board space constraints.

Replacement Considerations

Direct substitutes include other single-channel comparators with similar propagation delays and supply currents. Verify that replacement parts support the required 2.1V minimum supply voltage and offer compatible rail-to-rail input/output specifications. Package compatibility must be confirmed if PCB footprint changes are not permitted.
