**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.
