Overview
The MAX9075EXK is a single-channel analog comparator from the Maxim Integrated portfolio, housed in a 5-pin SC-70 surface-mount package. It operates on a single supply voltage ranging from 2.1V to 5.5V with a typical quiescent current of 3µA per device. The component features a propagation delay of 580ns and rail-to-rail output capability. Input specifications include a maximum offset voltage of 8mV and a common-mode rejection ratio of 60dB. It supports an industrial operating temperature range from -40°C to +85°C.
Feature Summary
- Ultra-small footprint suitable for portable applications
- Ground-sensing input capability without phase inversion
- Rail-to-rail output drive performance
- Low-power operation optimized for single-supply systems
Applications
- Battery-powered consumer electronics
- Threshold detection and discrimination circuits
- Keyless entry system interfaces
- Infrared (IR) receiver front-ends
- Digital line receiving termination
Procurement Notes
Verify the specific suffix 'EXK' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging configuration and lead-free status. Ensure the ordering part number matches the required quantity format and that the component is currently active within the Analog Devices product lifecycle before finalizing procurement plans.
Selection Notes
Select this comparator when minimizing board space and power consumption are critical constraints in single-supply designs. The device is appropriate for applications requiring ground-referenced inputs and fast response times under low-voltage conditions. Consider the SC-70 package thermal characteristics and ensure the load requirements align with the specified output drive capabilities.
Part Context
This component belongs to the MAX907x family of ultra-low-power comparators designed for battery-operated devices. The series emphasizes minimal static current draw while maintaining sufficient speed for general-purpose signal processing tasks. The single-channel variant provides a cost-effective solution for compact embedded systems where multiple comparison functions are not required.
Replacement Considerations
The MAX9075EXKT is the tape-and-reel version of the MAX9075EXK. Verify if the MAX9077 dual-channel variant serves as a functional alternative if additional channels are needed, ensuring pin compatibility or redesigning the layout accordingly.
