LM2907MX from Texas Instruments, in a SOIC-14. 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 | TACH+ | input | Positive terminal for the tachometer input signal, which feeds the noninverting input of the internal Schmitt-trigger comparator. |
| 2 | CP1 | output | A capacitor on this pin is charged to VCC/2 by a 180 µA typical constant current source at the start of each positive half cycle and discharged at the same rate during negative half cycles. |
| 3 | CP2 | output | The charge pump sources current equal to the absolute value of the CP1 capacitor current, and a parallel resistor and capacitor on this pin filter the pulses into the output voltage. |
| 4 | IN+ | input | Noninverting input to the high-gain op amp, with input voltage limited to 0 V to 28 V on the 14-pin device. |
| 5 | EMIT | output | Emitter of the bipolar junction output transistor. |
| 6 | NC | unconnected | No connect. |
| 7 | NC | unconnected | No connect. |
| 8 | COL | output | Collector of the bipolar junction output transistor, which may be taken above VCC up to a maximum VCE of 28 V. |
| 9 | V+ | power_in | Supply voltage pin; absolute maximum supply voltage is 28 V. |
| 10 | IN- | input | Inverting input to the high-gain op amp, with input voltage limited to 0 V to 28 V on the 14-pin device. |
| 11 | TACH- | input | Negative terminal for the tachometer input signal, which feeds the noninverting input of the internal Schmitt-trigger comparator; input voltage limited to 0 V to 28 V on the 14-pin device. |
| 12 | GND | power_in | Ground reference for the device. |
| 13 | NC | unconnected | No connect. |
| 14 | NC | unconnected | No connect. |
