  ADC‐DAC Pi Zero The ADCDAC Pi Zero is compatible with all Raspberry Pi models from the A+ and B+ onwards. The ADC‐DAC Pi Zero is a 2 channel 12 bit analogue to digital converter and 2 channel 12 bit digital to analogue converter designed to work with the Raspberry Pi. Designed for the same footprint as the Raspberry Pi Zero the ADC‐DAC Pi Zero is also compatible with full size Raspberry Pi models. The ADC‐DAC Pi Zero is based on the Microchip MCP3202 A/D converter containing 2 analogue inputs with 12 bit resolution with a Microchip MCP4822 dual channel 12‐bit DAC with internal voltage reference. Power to the board is provided through the host Raspberry Pi using the GPIO port. Only one ADC‐DAC Pi Zero can be used on a Raspberry Pi but the extended pins on the GPIO connector allow you to stack the ADC‐DAC Pi Zero along with other expansion boards. Mounting holes on the board can be used to securely fit the board on your Raspberry Pi. As the ADC‐DAC Pi Zero uses the same footprint as the Raspberry Pi Zero only two of the mounting holes can be used on the larger Raspberry Pi models. The A/D and D/A converters communicate with the Raspberry Pi through the SPI interface. Max ADC Sample Rate: 100,000 samples per second Max ADC Sample Rate under Python on a Pi 2: 12,000 samples per second                                             https://uk.pi‐supply.com/products/adc‐dac‐pi‐zero/3‐20‐19
