The ADS7830 is an 8-channel, 8-bit analog-to-digital converter designed for reading multiple analog inputs over an I2C interface. It is commonly used with microcontrollers like Arduino and ESP32 to sample sensors, potentiometers, or other analog signals with minimal wiring.
| Pin | 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. |
A7 |
analog | Analog input channel 7 for voltage measurement by the ADS7830. |
A6 |
analog | Analog input channel 6 for voltage measurement by the ADS7830. |
A5 |
