Along with the voltage you need to check the polarity of the device and the powerpack
The polarity of the adapter cord and plug must match the polarity of the device, meaning that the positive contact of the plug must mate with the positive contact in the receptacle, and the negative plug contact must mate with the negative receptacle contact. Since there is no standardization of these plugs, a polarity symbol is typically printed on the case indicating which type of plug is needed.
MCP3008 ADC-DAC
Features and Specifications
- 8-Channel 10-bit ADC IC
- Communication protocol: Serial SPI interface
- Operating voltage 2.7V to 5V
- ADC method: Successive Approximation (SAR)
- Sampling Rate: 200ksps and 75ksps for 5V and 2.7V resp.
- Available in 16-pin PDIP, and SOIC packages
The MCP3008 is an 8-Channel 10-bit ADC IC, so it can measure 8 different analog voltage with a resolution of 10-bit. It measures the value of analog voltage from 0-1023 and sends the value to a microcontroller or microprocessor through SPI communication. It can operate on both 3.3V and 5V and hence it can be used with 5V microcontroller as well as with 3.3V systems like the Raspberry Pi. It uses the SAR method to convert the Analog voltage to digital value; it might not be the fastest and precise ADC in the market but is the cheapest and easy to use one.
