**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.
MCP4725A0T-E/CH: 0110 000U 0x60 - 0x61
MCP4725A1T-E/CH: 0110 001U 0x62 - 0x63
MCP4725A2T-E/CH: 0110 010U 0x64 - 0x65
MCP4725A3T-E/CH: 0110 011U 0x66 - 0x67
