Serial data input pin. This pin inputs serial data with a data length of 14 bits.
This pin outputs the MSB data in the 14-bit shift register.
Shift clock input pin. The input signal from the DI pin enters the 14-bit shift
register at the rising edge of the shift clock pulse.
When the LD pin inputs the High-level signal, shift register value is loaded to
the decoder and the D/A output register.
8-bit D/A output with OP-amp.
