Serial data input pin. This pin inputs serial data with a data length of 12
bits. (Do not leave the pin floating.)
This pin outputs the MSB data in the 12-bit shift register at the CLK falling
edge.
Shift clock input pin. The input signal from the DI pin enters the 12-bit shift
register at the rising edge of the shift clock pulse. (Do not leave this pin
floating.)
When the LD pin inputs the High-level signal, shift register value is loaded
to the decoder and the D/A output register. (Do not leave this pin floating.
When data is not transferred, fix the pin to the “Low” level.)
8-bit D/A output with op amp.
MCU interface and OP amp power-supply pin.
MCU interface and OP amp GND pin.
D/A converter reference power (High) input pin.
D/A converter reference power (Low) input pin.
