Overview
The LM2901S14-13 is a quad differential voltage comparator manufactured by Diodes Incorporated, housed in an SO-14 package. It operates from a single supply of 2V to 36V or dual supplies of ±1V to ±18V. The device features a typical input offset voltage of 2mV and a maximum of 7mV at +25°C. Supply current is 0.9mA typ at 5V. Input bias current is 25nA typ. Output saturation voltage is 100mV typ at 4mA sink current. Response time is 1.3µs typ.
Feature Summary
- Quad differential comparators with very low input offset voltage specifications
- Wide power supply range supporting both single and split supply operation
- Low power supply current drain that remains independent of the supply voltage magnitude
- Output voltage compatible with TTL, MOS, and CMOS logic families
Applications
- Direct interface with TTL and CMOS logic circuits
- MOS logic interfacing where low power drain is advantageous
- Precision voltage comparison applications requiring low offset voltage
Procurement Notes
Verify the specific ordering suffix matches the required package type and tape & reel quantity. Confirm RoHS compliance status for the intended manufacturing process. Ensure the component grade meets the application's offset voltage requirements. Check datasheet revision history for any parameter updates before finalizing procurement.
Selection Notes
Select this part when four independent comparators are needed in a single package. Consider the SO-14 footprint constraints against available board space. Evaluate the 2mV typical offset voltage against system accuracy needs. Verify that the open-collector output configuration aligns with the downstream logic requirements.
Part Context
This component belongs to the LM2901/2903 series of precision voltage comparators. The series includes dual and quad variants designed for general-purpose analog comparison tasks. The LM2901 specifically provides four channels, whereas the LM2903 offers two. Both share similar electrical characteristics and pinout compatibility within their respective channel counts.
Replacement Considerations
LM2901AT14-13: Offers lower offset voltage (1mV typ) in the same TSSOP-14 package. LM2901S14-13: Identical specification but different package variant if SO-14 is preferred over TSSOP-13. Cross-reference with LM2903S14-13 if only two comparators are required.
