Pinout
Here is a brief overview of its pin functions:
1. VDD: Power supply pin (typically 2.7V to 5.5V).
2. CH0/CH1: Analog input channels. These are the differential inputs where the analog signals to be converted are applied.
3. VREF: Voltage reference input pin. The voltage applied here determines the reference for the ADC conversion.
4. AGND: Analog ground pin. Used as a ground reference for the analog inputs.
5. CS/SHDN: Chip Select/Shutdown pin. This is used to initiate a conversion and power down the device.
6. DIN: Data input pin. Used to receive data from the microcontroller, such as configuration and channel selection bits.
7. DOUT: Data output pin. Outputs the converted digital data back to the microcontroller.
8. SCK: Serial Clock pin. It is used to synchronize data transfer between the ADC and the microcontroller.
These pins allow the MCP3202 to interface with microcontrollers using the SPI protocol for data communication.
