Overview
The FAN256L8X is a dual low voltage comparator from onsemi, packaged in an 8-lead MicroPak (1.6mm x 1.6mm) with tape and reel packing. It operates on a single power supply ranging from 1.6V to 5.5V. The device features rail-to-rail common-mode input voltage range, push-pull output circuitry, and internal hysteresis. Typical supply current is 7µA per comparator. Operating temperature range is -40°C to +85°C.
Feature Summary
- Rail-to-rail common-mode input voltage range
- Push-pull output stage capable of driving up to 5.0mA load
- Internal hysteresis for noise immunity
Applications
- Mobile Phones
- Alarm and Security Systems
- Personal Digital Assistants
Procurement Notes
Verify the specific ordering suffix 'L8X' corresponds to the 5000-unit tape and reel packaging configuration. Confirm that the operating temperature range of -40°C to +85°C meets your system requirements. Ensure the 8-lead MicroPak package dimensions align with your PCB land pattern design.
Selection Notes
Select this component when a dual comparator with very low supply current is required for battery-powered applications. The wide supply voltage range supports 1.8V, 3.0V, and 5.0V systems. The small MicroPak package is suitable for space-constrained designs.
Part Context
The FAN256L8X belongs to the FAN256 series of dual low voltage comparators manufactured by onsemi. It is designed for portable electronics requiring high efficiency and minimal power consumption while maintaining reliable signal comparison capabilities across various supply voltages.
Replacement Considerations
Check datasheets for other dual comparators in the MicroPak-8 package with similar supply current and voltage ranges. Verify pin compatibility and electrical characteristics before substitution.
FAQ
What is the typical supply current per comparator?
