Overview
The LM2901VDR2 is a single-supply quad comparator from onsemi, housed in a 14-pin SOIC package. It operates within a supply voltage range of 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. Key electrical characteristics include a typical input bias current of 25 nA and an input offset voltage of ±7.0 mV. The device features open-collector outputs capable of sinking up to 16 mA, with a typical response time of 1.3 µs. It supports an operating temperature range from -40 °C to +125 °C.
Feature Summary
- Supports single or split supply operation across a wide voltage range
- Features low input bias current and low output saturation voltage
- Includes ESD clamps on inputs for increased reliability
- Outputs are compatible with TTL and CMOS logic families
Applications
- Level detection in consumer, automotive, and industrial electronics
- Low-level sensing applications
- Memory circuit implementations
Procurement Notes
Verify the specific suffix 'V' indicates the extended temperature rating of -40 °C to +125 °C compared to standard variants. Confirm the 'DR2' suffix corresponds to the SOIC-14 tape and reel packaging format. Ensure compliance requirements such as RoHS and Pb-Free status match project specifications before finalizing procurement orders.
Selection Notes
Select this component when high gain and wide bandwidth are required for level detection tasks. Consider the LM2901V variant specifically for environments requiring operation up to +125 °C. Evaluate the open-collector output structure for compatibility with external pull-up resistors needed for specific logic voltage levels.
Part Context
This device belongs to the LM2901 family of single supply quad comparators manufactured by onsemi. It shares architectural similarities with the LM339 and LM239 series but is optimized for wider supply voltage ranges and higher temperature operation in the 'V' suffix version. The component is designed for robust performance in demanding electronic environments.
Replacement Considerations
LM2901DR2G serves as a direct functional replacement within the same product family, maintaining identical pinout and electrical specifications while adhering to updated manufacturing standards.
