Name & Function
+5 V DC power supply pins.
Ground pins.
Clock input pin. The input voltage is a TTL level.
Analog signal input pin. The analog data to be converted is input to
this pin. The input voltage range is 3V to 5V (VRB to VCC).
8-bit resolution A/D converter outputs.
The output voltage is a TTL level.
Also, D1 pin is an MSB and D8 pin is a LSB.
Reference voltage output pin. This pin outputs 0.6 x VCC [V] (Typ.
3V). An 1µF or more capacitor having superior frequency
characteristic should be connected to this pin. The capacitor must
be connected near the device.
An intermediate voltage output pin. An intermediate voltage
between VCC and VRB (Typ. 4V) is output from this pin. Normally
this pin is left open.
