Function

O 8bit D/A outputs with OP-AMP

- Digital section Power Supply Pin

- Digital section Ground Pin

- OP-AMP and D/A section Power Supply

- OP-AMP and D/A section Ground

I (SEL=High:CS I/F)

In AUTO READ operation and ECL operation, the address

of EEPROM is selected by the EA0 and the EA1 pins.

(SEL=Low:LD I/F)

The address of EEPROM is selected by the EA0 and the

EA1 pins.

I When the ECL pin receives high pulse, the data in

EEPROM is automatically loaded to each corresponding

D/A, starting from AO1 to AO12 in order. Then each D/A

output is settled to pre-determined value.

I Input Data Format Select Pin

SEL=High : CS I/F

SEL=Low : LD I/F

After power-up, this pin should be kept either at "high"

or "Low."
