Overview
The MAX9119EXK-T is a nanopower analog comparator from the MAX9117–MAX9120 family, manufactured by Analog Devices/Maxim Integrated. It operates on a single supply voltage ranging from +1.6V to +5.5V with a typical supply current of 350nA at +1.6V and 450nA at +5V. The device features a CMOS push-pull output stage capable of sourcing and sinking up to ±5mA, providing rail-to-rail output swing. It lacks an internal reference but includes 4mV of internal hysteresis. The input common-mode voltage range extends 200mV beyond the supply rails (Beyond-the-Rails). It is housed in a space-saving 5-pin SC-70 package.
Feature Summary
- Ultra-low power consumption with 350nA supply current
- CMOS push-pull output stage for rail-to-rail swing
- Input voltage range extends 200mV beyond supply rails
- Internal hysteresis prevents oscillation
Applications
- 2-cell battery monitoring and management systems
- Mobile communications devices
- Notebooks and PDAs
- Threshold detectors and discriminators
- Telemetry and remote sensing systems
Procurement Notes
Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the absence of an internal reference distinguishes this part from the MAX9117/MAX9118 variants. Ensure the design accommodates the push-pull output configuration rather than open-drain requirements. Check for RoHS compliance status indicated by the '+' suffix if applicable to your manufacturing standards.
Selection Notes
Select the MAX9119EXK-T when a push-pull output is required without the overhead of an internal reference. It is suitable for applications needing Beyond-the-Rails inputs and ultra-low static current. Compare against MAX9120 if an open-drain output is preferred for mixed-voltage logic interfacing. Consider MAX9117/MAX9118 if an integrated 1.252V reference simplifies the external circuit design.
Part Context
This component belongs to the MAX9117–MAX9120 series of SC70 nanopower comparators. The series differentiates parts based on output type (push-pull vs. open-drain) and the presence of an internal reference. The MAX9119 specifically combines the push-pull drive capability with the lower 350nA current draw of the non-reference variants, optimizing it for low-power signal conditioning tasks.
Replacement Considerations
Public confirmed substitute part numbers are not available in the provided documentation.
