Overview
The LM2901DG is a quad precision voltage comparator manufactured by onsemi in a SOIC-14 package. It operates from a single supply 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, an input offset voltage of ±2.0 mV (max ±7.0 mV), and a response time of 1.3 µs. The device features low output saturation voltage of 130 mV at 4.0 mA sink current and includes ESD clamps on inputs.
Feature Summary
- Supports single supply operation from 3.0 V to 36 V and split supply operation from ±1.5 V to ±18 V.
- Features low input bias current of 25 nA and low input offset voltage for precision applications.
- Includes ESD protection clamps on inputs to increase reliability without affecting device operation.
- Outputs are compatible with TTL, DTL, ECL, MOS, and CMOS logic families.
Applications
- Level detection circuits
- Low-level sensing applications
- Memory applications
Procurement Notes
Verify the specific suffix 'DG' corresponds to the SOIC-14 package and Pb-Free status as listed in the ordering information. Confirm that the component meets RoHS compliance requirements if applicable to your manufacturing process. Ensure the operating temperature range aligns with your system's environmental specifications before finalizing procurement.
Selection Notes
Select this component when high gain and wide bandwidth are required for level detection or sensing tasks. Consider the LM2901DG over variants like LM239 if lower input offset voltage and tighter performance tolerances are necessary for the application design.
Part Context
This part belongs to the LM339/LM2901 family of single supply quad comparators designed for consumer, automotive, and industrial electronic applications. It shares architectural similarities with the LM239 but offers improved precision characteristics suitable for more demanding signal conditioning tasks.
