ADS7830 to 8-kanałowy, 8-bitowy przetwornik analogowo-cyfrowy przeznaczony do odczytu wielu wejść analogowych przez interfejs I2C. Jest często używany z mikrokontrolerami takimi jak Arduino i ESP32 do pomiaru czujników, potencjometrów lub innych sygnałów analogowych przy minimalnej liczbie przewodów.
| Pin | Sygnał | Opis |
|---|---|---|
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. |
