Overview
The LM2901DR2G is a single-supply quad comparator manufactured by onsemi, housed in a 14-pin SOIC package. It operates within a power supply range of 3.0 V to 36 V for single supply and ±1.5 V to ±18 V for split supply configurations. The device features low input bias current (typical 25 nA) and low output saturation voltage (typical 130 mV at 4.0 mA). Electrical characteristics include a response time of 1.3 µs, an input offset voltage maximum of 7.0 mV, and an operating temperature range from -40°C to +105°C.
Feature Summary
- Supports both single and split power supply operations across a wide voltage range
- Features low input bias current and low output saturation voltage for efficient signal detection
- Includes ESD clamps on inputs to enhance reliability without affecting operation
- Outputs are compatible with TTL and CMOS logic families
Applications
- Level detection in consumer electronics
- Low-level sensing in industrial applications
- Memory interface circuits
- Automotive electronic systems
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm package type and reel specifications. Ensure the component meets required environmental standards such as RoHS compliance. Confirm that the selected variant aligns with the intended operating temperature range and automotive qualification requirements if applicable to the design.
Selection Notes
Select this component when high gain and wide bandwidth are required for level detection or sensing tasks. Consider the open-collector output capability for wired-AND configurations. Evaluate the input common mode voltage range relative to the ground reference. Ensure the supply voltage stays within the specified limits to maintain performance and prevent damage.
Part Context
This device belongs to the LM2901 family of single supply quad comparators produced by onsemi. It shares functional similarities with other members like the LM339 and LM239 but is optimized for broader supply voltage ranges. The DR2G suffix indicates a tape and reel packaging format suitable for automated surface-mount assembly processes.
Replacement Considerations
NCV2901DR2G is a qualified alternative offering automotive-grade specifications.
