The serial port can be used as a dedicated analog bus and kept inactive while the DAC8043 is in use. Serial interfacing reduces the complexity of opto or transformer isolation applications. The DAC8043 contains a 12-bit serial-in, parallel-out shift register, a 12-bit DAC register, a 12-bit CMOS DAC, and control logic. Serial input (SRI) data is clocked into the input register on the rising edge of the clock (CLK) pulse. When the new data word had been clocked in, it is loaded into the DAC register by taking the LD input low. Data in the DAC register is converted to an output current by the D/A converter.
