... SHUTDOWN MODE Shutdown mode can be entered by using either hard- SS ware or software commands. The hardware pin (SHDN) is only available on the MCP4821. During Shutdown mode, the supply current is isolated from most of the internal circuitry. The serial interface remains active, thus allowing a Write command to bring the device out of Shutdown mode ...
