Product Overview
The LM2901 is a Texas Instruments quad differential comparator in the Signal_Chain category. Its device description identifies four independent voltage comparators, with quiescent current independent of supply voltage. The LM2901 family comparison table lists a 2 to 30 V supply voltage range, 1 to 2.5 mA total supply current, and 1.3 µs typical response time.
Input-related parameters include a common-mode input voltage range that includes ground and a differential input voltage range equal to the maximum-rated supply voltage, listed as ±38 V in the feature list. The family comparison table lists input offset voltage as ±15 mV maximum over temperature, with a ±4 mV maximum listed condition, and input bias current of 25 nA typical and 250 nA maximum.
Package options include SOIC-14, PDIP-14, TSSOP-14, SOP-14, and SSOP-14. Thermal resistance junction-to-ambient is listed as 111.2 °C/W for SOIC-14, 136.6 °C/W for TSSOP-14, and 114.9 °C/W for PDIP-14. Applications should observe the non-B absolute maximum ratings, including 36 V supply voltage and 20 mA output current.

Procurement Notes
When requesting a quote for LM2901, 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.
