Features The ADC is a precision analog‑to‑digital converter (ADC).4 single-ended or 2 differential inputs, programmable comparator 2/3~16. The chip which can provide 16‑bit sampling precision, using an ultra‑small, an MSOP‑10 package.It's main function is detecting analog signal and convert it to digital signal. Power supply 3.3V, analog input voltage VDD, GND programmable data speed rate 8sps to 860sps.Internal PGA supports sampling precision 16-bit, I2C port through pin select addresses channels quantity. You can connect analog sensors, such as joystick, NTC, temperature, dust sensor, for R-a-s-p-b-e-r-r-y P-i through this converter, and read collected signal. Internal NPT support data through I2C compatible series port to transmit, there are 4 channel I2C address that can be choose, working power supply only need 3.3V Specifications: Compatibility: For R-a-s-p-b-e-r-r-y P-i 3/2/B+ Size: 6.5*3cm/2.5*1.1in Weight: 15g(approx.) Package Includes: 1 x ADC Module Note: Please note that the new type and old type of this product will be sent randomly, and make sure you will not mind before ordering. Package List
