Overview
The HA17903FPJ-E is a dual comparator integrated circuit manufactured by Renesas Electronics Corporation. It operates with a wide supply voltage range of 2V to 36V and features very low supply current consumption of 0.8mA. The device provides small input bias current (25nA), small input offset current (3nA), and small input offset voltage (2mV). Its common mode input voltage range includes ground, and the output saturation voltage is 1mV at 5µA or 70mV at 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 of 0.8mA
- Small input bias current of 25nA
- Output voltage compatible with CMOS logic systems
Applications
- Limit comparator circuits
- Simple analog/digital converters
- Pulse/square wave/time delay generators
- Wide range VCO applications

Procurement Notes
Verify component authenticity through authorized distributors. Confirm package type matches FPJ specification. Check RoHS compliance status. Ensure storage conditions meet moisture sensitivity level requirements. Validate supplier documentation against Renesas official records.
Selection Notes
Select this component for applications requiring wide voltage operation and low power consumption. Consider its CMOS-compatible output for digital interface integration. Evaluate its low input offset characteristics for precision comparison tasks. Verify operating temperature range meets system requirements.
Part Context
The HA17903 series belongs to Renesas' legacy comparator product line, originally developed under Hitachi Semiconductor before corporate restructuring. This dual comparator family offers general-purpose performance suitable for various analog signal processing applications in industrial and consumer electronics.
Replacement Considerations
Compatible alternatives include LM319 from Fairchild Semiconductor and MB47393 from Fujitsu Semiconductor. Verify pin compatibility and electrical specifications before substitution.
