LM2903WDT from STMicroelectronics, in a SO-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 | Output 1 | output | Comparator 1 open-collector output with 250 mV typical saturation voltage at Isink = 4 mA and maximum 700 mV over operating temperature. |
| 2 | Inverting input 1 | input | Inverting input of comparator 1 with 25 nA typical input bias current and ±5 nA typical input offset current. |
| 3 | Non-inverting input 1 | input | Non-inverting input of comparator 1 with 25 nA typical input bias current and ±5 nA typical input offset current. |
| 4 | VCC- | power_in | Negative supply voltage; 0 V for single supply operation (0 to +36 V) or -18 V for split supply operation (±1 V to ±18 V). |
| 5 | Non-inverting input 2 | input | Non-inverting input of comparator 2 with 25 nA typical input bias current and ±5 nA typical input offset current. |
| 6 | Inverting input 2 | input | Inverting input of comparator 2 with 25 nA typical input bias current and ±5 nA typical input offset current. |
| 7 | Output 2 | output | Comparator 2 open-collector output with 250 mV typical saturation voltage at Isink = 4 mA and maximum 700 mV over operating temperature. |
| 8 | VCC+ | power_in | Positive supply voltage; +2 V to +36 V for single supply operation or +1 V to +18 V for split supply operation. |
