L’ADS7830 est un convertisseur analogique-numérique 8 bits à 8 canaux, conçu pour lire plusieurs entrées analogiques via une interface I2C. Il est souvent utilisé avec des microcontrôleurs comme Arduino et ESP32 pour mesurer des capteurs, des potentiomètres ou d’autres signaux analogiques avec un câblage minimal.
| Broche | Signal | Description |
|---|---|---|
VIN |
power | Module supply input for the ADS7830 board, typically 3.3V or 5V. |
GND |
ground | Ground reference for power, I2C, and analog input measurements. |
SCL |
SCL | I2C clock line from the microcontroller to the ADS7830. |
SDA |
SDA | I2C data line for commands and ADC conversion results. |
REF |
reference | ADC reference voltage input that sets the conversion full-scale range. |
COM |
analog | Common analog input/reference node used for ADS7830 input modes. |
AD0 |
digital | I2C address select pin; tie high or low to choose the device address. |
AD1 |
digital | I2C address select pin; tie high or low to choose the device address. |
