DESCRIPTION
The WM2613 is a 12-bit voltage output, resistor string,  digital-to analogue converter. The DAC can be powered down under software or hardware control, reducing power consumption to 10nA.
The device has an 8-bit microcontroller compatible parallel interface. The eight data  LSBs, the four data MSBs, and the three control bits are written using three different addresses.
