/** MCP4725 class.
* Used for interfacing with a mcp4725 12-Bit Digital-to-Analog Converter.
- * There is an accompanying test suite program "MCP_4725_Library_Test" that can
- * be used to test this library.
+ * To convert between the 12bit dac_value and Vout, use the following formula: dac_value = (Vout*4096/Vref), where Vref is the voltage
+ * connected to the Vdd pin of the device. Typically Vdd will be 3.3volts.
+ *
+ * Note: There is an accompanying test suite program "MCP_4725_Library_Test" that can be used to test this library.
