Can I connect a ADC0804LCN to a raspberry pi ?


  • I am not expert on electrical engineering, but on page 4 of the referenced manual there is the following Digital Output Specification: i.imgur.com/0w2PPKz.png Now, you just need to check if the Raspberry Pi allows these voltages and amperes.

If you have any choice, you might be better at choosing an A/D converter which has an SPI interface, such as MCP3008 from Microchip. It will be far more easy to "talk" with from the raspberry pi as the latter also has an SPI interface available through the GPIO pins.

Adafruit has a nice tutorial on how to use this chip with the Raspberry Pi.
