Overview
The LM2901NSR is a quad differential comparator manufactured by Texas Instruments, housed in a 14-pin SOIC surface-mount package. It operates on a supply voltage range of 2 V to 30 V with a typical operating supply current of 2.5 mA. The device features an input offset voltage of 7 mV and an input bias current of 250 nA. Output stages are compatible with CMOS and TTL logic families, providing a per-channel output current capability of 6 mA. The unit supports a response time of 1.3 µs and functions within a temperature range from -40°C to +125°C.
Feature Summary
- Integrates four independent differential comparators into a single compact integrated circuit.
- Provides versatile logic compatibility through outputs designed for both CMOS and TTL interfacing.
- Operates effectively across a wide dual-supply voltage range starting from 2 V.
Applications
- General-purpose analog signal comparison circuits
- Voltage monitoring systems requiring low-power operation
- Interface modules between analog sensors and digital logic controllers
Procurement Notes
Verify the specific manufacturer designation and package marking against official Texas Instruments documentation to confirm authenticity. Ensure the ordering suffix matches the required reel quantity and tape-and-reel specifications. Cross-reference the component date code and RoHS compliance status with the latest datasheet revisions before finalizing procurement orders.
Selection Notes
Select this component when a quad comparator configuration is required in a surface-mount design. The 14-pin SOIC footprint offers a balance between pin count and board space efficiency. Consider the 2.5 mA supply current and 6 mA output drive capability against system power budgets and load requirements to ensure adequate performance margins.
Part Context
This part belongs to the LM2901 series of analog comparators produced by Texas Instruments. The series provides multiple channel options in various packages, including through-hole and surface-mount variants. The NSR suffix specifically denotes the small-outline integrated circuit package type with reel packaging for automated assembly processes.
