DA converter lower standard voltage (VrefL) input terminal
10bit D/A output（CH3）
10bit D/A output（CH4）
10bit D/A output（CH5）
The reverse LSB and MSB of data designation 10bit in 14bit.
All ch analog output L fixed
10bit D/A output（CH6）
10bit D/A output（CH7）
10bit D/A output（CH8）
DA converter upper standard voltage (VrefH) input terminal
Power source terminal
10bit D/A output（CH9） （BU2506FV : test terminal）
10bit D/A output（CH10） （BU2506FV : test terminal）
This outputs bit data of LSB of 14bit shift register.
LD terminal. When High level is input, the value of 14bit shift
register is loaded to decoder and D/A output register.
Shift clock input terminal. At rise of shift clock, the signal from DI
terminal is input to 14bit shift register.
Serial data input terminal. Serial data whose data length is 14bit
(address 4bit + data 10bit) is input.
10bit D/A output（CH1）
10bit D/A output（CH2）
