LM2907M from Texas Instruments, in a SOIC-14. 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 | Charge pump timing capacitor pin, charged and discharged at 180 µA typical by VCC/2 steps at each half cycle. |
| 3 | CP2 | output | Charge pump output that sources current equal to the absolute capacitor current on CP1; integrates with R1-C2 network to produce output voltage. |
| 4 | IN+ | input | Noninverting input of the high-gain op amp; common-mode voltage range 0 to VCC-1.5 V. |
| 5 | EMIT | output | Emitter of the bipolar junction transistor output stage; can source up to 10 mA at VE = VCC-2 V. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | COL | output | Collector of the bipolar junction transistor output stage; can sink 40-50 mA or be taken above VCC to maximum VCE of 28 V. |
| 9 | V+ | power_in | Supply voltage input with operating range 0-28 V DC; total supply current typically 3.8-6 mA for zener regulator variant. |
| 10 | IN- | input | Inverting input of the high-gain op amp; common-mode voltage range 0 to VCC-1.5 V. |
| 11 | TACH- | input | Negative terminal for the input signal that leads to the noninverting terminal of the internal Schmitt-Trigger comparator; differential input devices require both inputs within 0-28 V. |
| 12 | GND | power_in | Ground connection providing the reference voltage for all circuit operations. |
| 13 | NC | unconnected | No internal connection. |
| 14 | NC | unconnected | No internal connection. |
