Overview
The AP393SL-13 is a dual precision voltage comparator manufactured by Diodes Incorporated, designed for single or split power supply operation. It features a wide supply voltage range from 2.0V to 36V and includes two independent comparators with a maximum offset voltage of 5.0mV at 25°C. The device operates with a low supply current drain of 0.4mA typical, which remains independent of the supply voltage magnitude. Input common-mode voltage ranges include ground, allowing sensing near zero potential. The output stage provides open-collector compatibility with TTL, CMOS, and MOS logic systems.
Feature Summary
- Wide supply voltage range supporting both single and dual power configurations
- Low input biasing current and minimal offset voltage for high precision applications
- Input common-mode voltage range extends to ground level
- Output saturation voltage compatible with standard digital logic families
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- MOS clock timers and multivibrators
- High voltage digital logic gates
Procurement Notes
Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status as indicated in official documentation. Check datasheet revision history for any updates to electrical characteristics or pin assignments prior to integration into final designs.
Selection Notes
Evaluate thermal performance based on package type and ambient conditions. Ensure input signals remain within specified common-mode voltage limits to prevent latch-up or incorrect switching states. Consider hysteresis requirements to prevent oscillation during signal transitions in noisy environments.
Part Context
This component belongs to the AP393 series of low power dual comparators. It serves as a replacement for legacy devices requiring precise voltage comparison with low power consumption. The SOP-8L package offers surface mount convenience while maintaining electrical performance suitable for portable and battery-operated equipment.
Replacement Considerations
AP393SG-13 (Same family, different packaging)
FAQ
Can the AP393 handle differential input voltages exceeding the supply voltage?
Yes, the differential input voltage may exceed V+ without damaging the device, provided the other voltage remains within the common-mode range.
Is power supply bypassing required for stable operation?
Standard PC board layout is helpful to reduce stray coupling. Bypassing is not strictly required to solve oscillation problems caused by capacitive coupling; adding positive feedback (hysteresis) is recommended instead.
