Overview
The HA17903PSD-E is a dual comparator manufactured by Renesas Electronics Corporation. It operates with a wide supply voltage range of 2V to 36V and features very low supply current of 0.8mA. The device includes small input bias current (25nA), small input offset current (3nA), and small input offset voltage (2mV). The common mode input voltage range includes ground, and the output saturation voltage is small at 1mV for 5µA and 70mV for 1mA. The output voltage is compatible with CMOS logic systems.
Feature Summary
- Wide supply voltage operation from 2V to 36V
- Very low supply current consumption
- Small input bias and offset characteristics
- CMOS logic compatible output
Applications
- Limit comparator circuits
- Simple analog/digital converters
- Pulse/square wave/time delay generators
- Wide range VCO applications
- MOS clock timer circuits
Procurement Notes
Verify the exact package type and suffix designation against official Renesas documentation to ensure compatibility with your design requirements. Confirm the operating temperature range and electrical specifications match your application needs before procurement.
Selection Notes
Consider the wide supply voltage range and low current consumption when selecting this component for battery-powered or energy-efficient designs. Ensure the CMOS logic compatible output meets the interface requirements of your downstream circuitry.
Part Context
The HA17903 series consists of dual comparators designed for versatile analog signal processing applications. These devices are suitable for various industrial and consumer electronics where precise voltage comparison and low power consumption are critical.
Replacement Considerations
Check for pin-compatible alternatives such as the LM319 or MB47393 if sourcing issues arise. Verify that any substitute part meets the same electrical specifications and package requirements.
