Overview
The LM2901VN is a quad voltage comparator manufactured by onsemi, designed for level detection and low-level sensing. It operates from a single supply of 3.0 V to 36 V or split supplies of ±1.5 V to ±18 V. The device features a maximum operating temperature of +125 °C and includes ESD clamps on the inputs. Electrical characteristics include a typical input bias current of 25 nA, an input offset voltage of ±7.0 mV, and a response time of 1.3 µs. The output saturation voltage is typically 130 mV at 4.0 mA sink current.
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 (typical) and low input offset voltage of ±7.0 mV (maximum).
- Includes ESD clamps on the inputs to increase reliability without affecting device operation.
- Output voltage is compatible with TTL, DTL, ECL, MOS, and CMOS logic families.
Applications
- Level detection in consumer, automotive, and industrial electronic applications.
- Low-level sensing circuits requiring high gain and wide bandwidth.
- Memory applications utilizing the comparator's differential input capabilities.
Procurement Notes
Verify the specific suffix 'VN' against the manufacturer's ordering information table, as the datasheet lists 'LM2901VDR2G' and 'LM2901VDTBR2G'. Confirm that the package type matches the required application constraints. Ensure compliance with RoHS and Pb-Free standards as indicated for this product family. Check for any specific automotive qualification requirements if the NCV prefix is necessary.
Selection Notes
Select this component when a quad comparator with extended high-temperature performance up to +125 °C is required. The LM2901V variant offers superior thermal stability compared to standard commercial grades. Consider the low input bias current for high-impedance signal sources. Verify that the open-collector output configuration aligns with the downstream logic interface requirements.
Part Context
The LM2901 series belongs to a family of single-supply quad comparators designed for general-purpose use. The 'V' suffix denotes an extended temperature range capability, specifically supporting operation up to +125 °C. This distinguishes it from other variants like the LM2901E which has a lower maximum operating temperature. The device shares pinouts and basic electrical characteristics with the LM339 and LM239 series.
Replacement Considerations
Public confirmed substitute part numbers include LM2901VDR2G and LM2901VDTBR2G from onsemi. Other manufacturers produce equivalent quad comparators such as the LM339 or MC3302, though specific parameter verification is required.
