CM1106-SOPTA from CIMO, in a MSOP-10. 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 | SCLK | input | Serial clock input for the SPI interface; the controller should be set to CPOL=0, CPHA=1 so SCLK idles low. |
| 2 | CS | input | Chip select input, active low, which frames SPI communication; CS must go high after 16 SCLK cycles in 16-bit mode to reset the SPI interface. |
| 3 | GND | power_in | Ground reference for the device. |
| 4 | AIN0 | passive | Analog input 0; analog input voltages must stay within GND-0.3 V to VDD+0.3 V per the absolute maximum ratings. |
| 5 | AIN1 | passive | Analog input 1; analog input voltages must stay within GND-0.3 V to VDD+0.3 V per the absolute maximum ratings. |
| 6 | AIN2 | passive | Analog input 2; analog input voltages must stay within GND-0.3 V to VDD+0.3 V per the absolute maximum ratings. |
| 7 | AIN3 | passive | Analog input 3; analog input voltages must stay within GND-0.3 V to VDD+0.3 V per the absolute maximum ratings. |
| 8 | VDD | power_in | Power supply input; absolute maximum VDD is -0.3 V to 7 V and the operating supply range is 2.5 V to 5 V. |
| 9 | DOUT/DRDY | output | Serial data output or data-ready indicator, active low; it can be pulled up to VDD through an internal 400 kΩ resistor enabled by default in the CONFIG register. |
| 10 | DIN | input | Serial data input for the SPI interface, used to write CONFIG register data and read-back commands. |
