|The MM110 module from Velleman is a breakout board which hosts a MCP4725A0T-E/CH DAC (Digital to Analogue Converter) integrated circuit, manufactured by Microchip, and capable of a 12-bit resolution. It integrates an EEPROM and has a I²C-Bus connection available (the address may be selected via the A0 jumper, by setting it to + or -; the other two bits from the bus’ address are internally fixed, thus you may connect the same bus to two DACs at most). The integrated circuit is powered by means of a single voltage, with a value between 2.7 and 5.5 volts (in our board it operates by means of the 5 V applied between the 5V and GND contacts). It has the rail-to-rail function available on the output, thus it may supply from 0 to 5 volts.|
The internal EEPROM allows to save the input configuration by means of the same I²C interface. The non-volatile memory allows the DAC to keep the input data, in case of blackout, so to represent the voltage corresponding to the analogue output, once that a power source is supplied.
