LM2903MS08ARDQ
GR · Comparators · MSOP-8
LM2903MS08ARDQ from GR, 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 | OUT1 | output | Output of comparator 1, which is an open-drain output so the logic-high level is set by an external pull-up and comparators can be wired-AND. |
| 2 | IN1- | input | Negative input of comparator 1; the differential input voltage range is stated as ±VCC. |
| 3 | IN1+ | input | Positive input of comparator 1; the differential input voltage range is stated as ±VCC. |
| 4 | GND | power_in | Ground reference pin; the datasheet states that all voltage values except differential voltages are referenced to network ground. |
| 5 | IN2+ | input | Positive input of comparator 2; the differential input voltage range is stated as ±VCC. |
| 6 | IN2- | input | Negative input of comparator 2; the differential input voltage range is stated as ±VCC. |
| 7 | OUT2 | output | Output of comparator 2, which is an open-drain output so the logic-high level is set by an external pull-up and comparators can be wired-AND. |
| 8 | VCC | power_in | Power supply pin; the datasheet states a single supply range of 2 V to 32 V (dual supply ±16 V). |
