LM2907MX-8 from Texas Instruments, in a SOIC-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 | TACH+ | input | Positive terminal for the input signal that leads to the noninverting terminal of the internal Schmitt-Trigger comparator. |
| 2 | CP1 | output | Capacitor charged up to VCC/2 by a constant current source of 180 µA typical at the start of every positive half cycle and discharged at the same rate at the beginning of negative half cycles. |
| 3 | CP2/IN+ | bidirectional | Charge pump capacitor node and noninverting input to the high gain op amp; these functions share this pin and are internally connected on 8-pin devices. |
| 4 | EMIT | output | Emitter of the bipolar junction transistor. |
| 5 | COL | output | Collector of the bipolar junction transistor. |
| 6 | V+ | power_in | Supply voltage. |
| 7 | IN- | input | Inverting input to the high gain op amp. |
| 8 | TACH-/GND | power_in | Negative terminal for the input signal to the Schmitt-Trigger comparator; internally connected to ground on 8-pin devices and must be tied to ground externally. |
