LM2903DMR2G from onsemi, in a MSOP-8. 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 | OUTA | output | Open-collector output of comparator A. Requires an external pull-up resistor to a positive supply (typically 3-30 V). Sinks current when the inverting input is above the non-inverting input. |
| 2 | IN A- | input | Inverting input of comparator A. Common-mode input voltage range includes ground; can operate from V- (GND) up to (VCC - 1.5 V). |
| 3 | IN A+ | input | Non-inverting input of comparator A. Common-mode input voltage range includes ground; can operate from V- (GND) up to (VCC - 1.5 V). |
| 4 | VEE/GND | power_in | Negative supply / ground pin. In single-supply operation, connect to 0 V (GND). Split supply operation is also supported. |
| 5 | IN B+ | input | Non-inverting input of comparator B. Common-mode input voltage range includes ground; can operate from V- (GND) up to (VCC - 1.5 V). |
| 6 | IN B- | input | Inverting input of comparator B. Common-mode input voltage range includes ground; can operate from V- (GND) up to (VCC - 1.5 V). |
| 7 | OUTB | output | Open-collector output of comparator B. Requires an external pull-up resistor to a positive supply (typically 3-30 V). Sinks current when the inverting input is above the non-inverting input. |
| 8 | VCC | power_in | Positive supply pin. Single-supply operation from 2 V to 36 V, or split-supply operation ±1 V to ±18 V. Low supply current (~0.4 mA typical) largely independent of supply voltage. |
