CIMO · Analog To Digital Converters (ADC) · MSOP-10
CM1103-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 | ADDR | input | I2C slave address selection pin; connect to GND, VDD, SDA, or SCL to select address per Table 4. |
| 2 | ALTER/RDY | output | Comparator output or conversion ready signal; open-drain output configurable via COMP_MODE register bit. |
| 3 | GND | power_in | Ground connection. |
| 4 | AIN0 | input | Analog input channel 0, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V. |
| 5 | AIN1 | input | Analog input channel 1, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V. |
| 6 | AIN2 | input | Analog input channel 2, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V. |
| 7 | AIN3 | input | Analog input channel 3, selectable as positive or negative input in differential configuration or single-ended mode; voltage range GND-0.3V to VDD+0.3V. |
| 8 | VDD | power_in | Positive supply voltage input; operating range 2.5V to 5V. |
| 9 | SDA | bidirectional | I2C serial data line, open-drain output; logic high threshold VIH=0.7VDD to VDD+0.3V, logic low threshold VIL=GND to 0.3VDD. |
| 10 | SCL | input | I2C serial clock input; logic high threshold VIH=0.7VDD to VDD+0.3V, logic low threshold VIL=GND to 0.3VDD. |
