Product details

Four comparators in a single 14-TSSOP — what that buys you on a mixed-voltage board

The LM2901PW packs four independent differential comparators into a 14-TSSOP package, each with an open-collector output that can sink up to 20 mA. The wide supply range of 2 V to 30 V (single supply) or ±1 V to ±15 V (dual supply) lets this part sit on a 24 V industrial backplane or a 3.3 V battery-powered board without a local regulator.

Temperature range and input offset — the specs that decide fit

Maximum input offset voltage is 7 mV at 30 V. Maximum input bias current is 0.25 µA at 5 V.

Frequently asked questions

What are the key electrical specifications of LM2901PW?

Four differential comparators with open-collector outputs. Supply range: 2 V to 30 V single, ±1 V to ±15 V dual. Maximum input offset: 7 mV at 30 V. Maximum input bias: 0.25 µA at 5 V. Quiescent current: 2.5 mA max. Output sink current: 20 mA typical. Operating temperature: -40°C to 125°C.

Can LM2901PW be used as a replacement for LM2901?

The LM2901PW is a surface-mount variant of the LM2901 base part number. It is functionally identical — same quad comparator core, same electrical specs — but packaged in a 14-TSSOP instead of the through-hole DIP or SOIC. If your board is laid out for a DIP-14 or SOIC-14 footprint, the TSSOP will not fit without a layout change.
