README
markdownCM5400-SOPTA
CIMO · Voltage Reference · SOP-8
CM5400-SOPTA from CIMO, in a SOP-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 | NC | unconnected | Not internally connected; it may be left floating or connected to external ground. |
| 2 | VIN | power_in | Supply input, 7.2V to 40V. |
| 3 | CAP | passive | A compensation capacitor is connected between the CAP and VOUT pins for stability when the load capacitance C1 exceeds 0.01μF. |
| 4 | GND | power_in | Ground reference. |
| 5 | TRIM | passive | Output voltage trim pin; an external potentiometer between VOUT and GND, with its wiper connected through a large resistor (e.g. 300kΩ), adjusts the output by about ±0.34% (CM5405), ±0.6% (CM5407) or ±0.7% (CM5400). |
| 6 | VOUT | output | Voltage reference output. |
| 7 | NC | unconnected | Must be left floating. |
| 8 | NC | unconnected | Must be left floating. |
