Overview
The AP393NG-U is a dual precision voltage comparator manufactured by Diodes Incorporated, housed in an 8-pin PDIP-8L package. It operates from a single supply of 2.0V to 36V or split supplies of ±1.0V to ±18V. The device features a maximum offset voltage of ±3mV and a low supply current drain of 0.4mA, independent of supply voltage. Input biasing current is 25nA with an input offset current of ±5nA. The output saturation voltage is 250mV at 4mA sink current.
Feature Summary
- Dual precision comparators designed for single power supply operation over a wide voltage range
- Low power supply current drain that remains independent of the magnitude of the power supply voltage
- Input common-mode voltage range includes ground even when operated from a single supply
- Output voltage compatible with TTL, DTL, ECL, MOS, and CMOS logic systems
Applications
- Limit comparators
- Simple analog to digital converters
- Pulse, squarewave and time delay generators
- Wide range VCO and MOS clock timers
- High voltage digital logic gates
Procurement Notes
Verify component authenticity through authorized channels as this part is marked Not Recommended for New Design. Confirm package integrity upon receipt, specifically checking for damage to the PDIP-8L housing. Ensure compliance with RoHS directives and lead-free finish requirements specified in the datasheet. Review product change notifications for any manufacturing updates prior to integration into final assemblies.
Selection Notes
Select this component for applications requiring high precision comparison with minimal offset voltage drift. The wide input common-mode range including ground simplifies circuit design by eliminating the need for dual supplies in many scenarios. Consider the low power consumption suitable for battery-operated devices. Verify interface compatibility with target logic families such as TTL or CMOS before implementation.
Part Context
The AP393 series consists of two independent precision voltage comparators designed for low power and low offset voltage performance. The NG suffix indicates a PDIP-8L package with a tube packing configuration. This specific variant is part of a legacy line not recommended for new designs, suggesting potential availability constraints compared to newer alternatives.
Replacement Considerations
Consult official documentation for direct substitutes. No public confirmed substitute part numbers are available in the provided source material.
