LM2903A-VR

3PEAK · Comparators · MSOP-8

LM2903A-VR from 3PEAK, in a MSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Out A output Open-collector output of comparator A, which can be wired-AND with other open-collector outputs and sinks up to 10 mA at VOL = 1.5 V.
2 -In A input Inverting input of comparator A, with common-mode range from 0 to VCC − 1.5 V at 25°C.
3 +In A input Non-inverting input of comparator A, with common-mode range from 0 to VCC − 1.5 V at 25°C.
4 V- power_in Negative supply or ground pin, for single supply of 2.5 V to 36 V or dual supply of ±1.25 V to ±18 V.
5 +In B input Non-inverting input of comparator B, with common-mode range from 0 to VCC − 1.5 V at 25°C.
6 -In B input Inverting input of comparator B, with common-mode range from 0 to VCC − 1.5 V at 25°C.
7 Out B output Open-collector output of comparator B, which can be wired-AND with other open-collector outputs and sinks up to 10 mA at VOL = 1.5 V.
8 V+ power_in Positive supply pin, 2.5 V to 36 V (42 V absolute maximum V+ − V−), with a 0.01 μF to 0.1 μF bypass capacitor recommended within 2 mm.
