Texas Instruments · Comparators · SOIC-14

LP2901DR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 1OUT output Output of comparator 1, an open-collector (uncommitted collector) output that can sink current from an externally supplied pull-up.
2 2OUT output Output of comparator 2, an open-collector output capable of sinking 30 mA at VO = 2 V.
3 VCC power_in Positive supply voltage input, operable from 3 V to 30 V (single supply) or split supplies, with ultra-low ~60 µA typical drain current.
4 2IN- input Inverting input of comparator 2; common-mode input voltage range includes ground.
5 2IN+ input Non-inverting input of comparator 2; common-mode input voltage range includes ground.
6 1IN- input Inverting input of comparator 1; common-mode input voltage range includes ground.
7 1IN+ input Non-inverting input of comparator 1; common-mode input voltage range includes ground.
8 3IN- input Inverting input of comparator 3; common-mode input voltage range includes ground.
9 3IN+ input Non-inverting input of comparator 3; common-mode input voltage range includes ground.
10 4IN- input Inverting input of comparator 4; common-mode input voltage range includes ground.
11 4IN+ input Non-inverting input of comparator 4; common-mode input voltage range includes ground.
12 GND power_in Ground/network reference pin; all voltage values except differential voltages are referenced to this pin.
13 4OUT output Output of comparator 4, an open-collector output capable of sinking 30 mA at VO = 2 V.
14 3OUT output Output of comparator 3, an open-collector output capable of sinking 30 mA at VO = 2 V.
