Product Overview
The LM2901DR is a Texas Instruments quad differential comparator in the Signal_Chain category. The device integrates 4 independent voltage comparators and is specified as a quad differential comparator, making it suitable for multi-channel voltage comparison functions within one package.
Recommended operation for the non-V device range is 2 to 30 V, with LM2901 family data showing 1 to 2.5 mA total supply current. Input specifications include ±9 mV maximum input offset voltage over temperature, ±4 mV maximum at 25°C, and 25 nA typical, 250 nA maximum input bias current. Typical response time is 1.3 µs.
LM2901DR is supplied in the SOIC (14) D package, with an 8.70 mm × 3.90 mm nominal body. The package thermal data includes 111.2 °C/W junction-to-ambient thermal resistance and 66.9 °C/W junction-to-case top thermal resistance. Outputs are TTL, MOS, and CMOS compatible, while the common-mode input voltage range includes ground.

Procurement Notes
When requesting a quote for LM2901DR, buyers should confirm the manufacturer, package or case, required quantity, target date code, compliance documents, packing method, destination country and expected delivery schedule.
If alternatives are acceptable, buyers should share the approved vendor list, required electrical or optical limits, package constraints and qualification requirements. Any alternative part should be reviewed by the buyer's engineering team before production use.
For analog and signal-chain sourcing, supply voltage, bandwidth, accuracy, noise level, package, temperature grade, input/output configuration and qualification requirements should be verified before approval.
FAQ
How many comparators are integrated in LM2901DR?
LM2901DR integrates 4 independent voltage comparators. The extracted device description identifies it as a quad differential comparator, so it can support four separate voltage comparison channels in one SOIC-14 package.
What supply voltage range is specified for LM2901DR?
The extracted datasheet facts list a 2 to 30 V supply voltage range for LM2901 family comparison data and for recommended operating conditions of non-V devices. Absolute maximum supply voltage for non-B versions is 36 V.
What package is used for LM2901DR?
LM2901DR uses the SOIC (14) D package with an 8.70 mm × 3.90 mm nominal body. The extracted thermal data is also specified for the D package with 14 pins.
What output logic families are compatible with LM2901DR?
The extracted feature list states that the LM2901DR output is compatible with TTL, MOS, and CMOS logic. This supports interfacing to those logic families when the surrounding circuit follows the device ratings.
