MCP4725 ADDRESS NOTES

The address of the MCP4725 in the demo sketches is set to 0x62 as that was the address of the sensor I had during writing. According to the datasheet the address has the following bit pattern:

  011000FFU   (so 0x6?)

  ***F = Factory set bit***
  ***U = User configurable bit***

This means you can have at most 8 MCP4725 in one I2C bus (without multiplexing). You have to specify the factory bits in your order, but not all shops might provide all versions.
