Overview
The LM2901NG is a quad analog comparator manufactured by onsemi in a PDIP-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 parameters include a typical input bias current of 25 nA, an input offset voltage of ±7.0 mV (max), and a response time of 1.3 µs. The device features open-collector outputs compatible with TTL and CMOS logic, with a maximum output sink current of 16 mA.
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 and low input offset voltage for precision sensing.
- Includes ESD clamps on inputs to increase reliability without affecting device operation.
- Outputs are compatible with TTL and CMOS logic families.
Applications
- Level detection circuits
- Low-level sensing applications
- Memory applications
Procurement Notes
Verify the specific ordering suffix 'N' corresponds to the PDIP-14 plastic through-hole package as defined in the official datasheet. Confirm that the component meets RoHS compliance and lead-free requirements. Ensure the operating temperature range aligns with the specified -40°C to +105°C limit for this variant. Cross-reference the manufacturer part number with authorized distributors to ensure authenticity.
Selection Notes
Select this component when a quad comparator with wide single-supply voltage capability is required. The low input bias current makes it suitable for high-impedance signal sources. Verify that the open-collector output configuration fits the system's pull-up requirements. Consider the PDIP-14 package constraints if board space allows for through-hole mounting.
Part Context
The LM2901 belongs to a family of single-supply quad comparators including the LM339 and LM239. These devices share similar functional architectures but may differ in temperature ranges and specific electrical characteristics. The LM2901 is designed for consumer, automotive, and industrial electronic applications requiring reliable voltage comparison.

FAQ
What is the input common mode voltage range?
The input common mode voltage range extends from ground (0 V) to VCC minus 1.5 V.
Can differential input voltages exceed the supply voltage?
Yes, differential input voltages can be larger than the supply voltages without damaging the comparator's inputs, provided they remain within the absolute maximum ratings.
