DESCRIPTION

Connect a capacitor of about 0.1µF.

Clock pin. Moreover all input pins are

TTL-CMOS compatible.

Digital GND.

Analog GND.

Chip enable pin. No signal (Output 0V) at “H”

and minimizes power consumption.

Connect a resistance 16 times “16R” that of

output resistance value “R”.

Set full scale output value.

Connect a capacitor of about 0.1µF.

Analog VDD.

Current output pin. Voltage output can be ob-

tained by connecting a resistance.

Inverted current output pin. Normally dropped

to analog GND.

Digital VDD.
