This pin inputs 12-bit serial data.
This pin outputs MSB bit data of 12-bit shift register.
Input signal from DI pin is inputted to 12-bit shift register
at rising of shift clock.
If input “H” level to LD pin, the data of 12-bit shift register
is loaded to the decoder and the register for D/A output.
These pins output analog data of 8-bit D/A converter with
OP amplifier.
