Overview
The LM2903VNG is a dual independent precision voltage comparator manufactured by onsemi. It supports single supply operation from 2.0 Vdc to 36 Vdc or split supplies of ±1.0 Vdc to ±18 Vdc. The device features very low current drain of 0.4 mA, independent of supply voltage. Input bias current is 25 nA typical, with input offset voltage up to 7.0 mV maximum at full temperature range. Operating ambient temperature ranges from -40°C to +125°C. It utilizes an open-collector output compatible with DTL, ECL, TTL, MOS, and CMOS logic levels.
Feature Summary
- Dual independent precision voltage comparators designed for wide voltage range single or split supply operation
- Low power consumption with current drain independent of supply voltage magnitude
- Input common mode voltage range extends to ground level
- Differential input voltage range equals the power supply voltage
Applications
- Consumer electronics
- Automotive applications
- Industrial electronics
Procurement Notes
Verify the specific ordering suffix 'VNG' against official manufacturer documentation to confirm package type and lead-free status. Ensure the component meets the required automotive or industrial specifications if applicable. Cross-reference the datasheet revision date with your design requirements to validate electrical characteristics and marking diagrams.
Selection Notes
Select this component when high gain and wide bandwidth are required alongside low power consumption. The extended temperature range makes it suitable for harsh environments. Verify that the open-collector output configuration aligns with the system's pull-up resistor requirements and logic interface standards.
Part Context
This part belongs to the LM2903 series of dual comparators from onsemi. It shares functional similarities with the LM393 and LM293 but offers improved offset voltage specifications. The 'V' suffix typically denotes an extended temperature range variant compared to standard commercial grade parts.
