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. |
