+VCC  
Power Supply Input. The +VCC range for the AD78ꢀ3 is from 2.2 V to 5.25 V. Both +VCC pins should be connected  
directly together.

Reference Input for the AD78ꢀ3. An external reference must be applied to this input. The voltage range for the  
external reference is 1.0 V to +VCC. For specified performance, it is 2.5 V.

PENIRQ  
DOUT  
Pen Interrupt. CMOS logic open-drain output (requires 10 kΩ to 100 kΩ pull-up register externally).  
Data Out. Logic Output. The conversion result from the AD78ꢀ3 is provided on this output as a serial data stream.  
The bits are clocked out on the falling edge of the DCLK input. This output is high impedance when CS is high.

BUSY Output. Logic Output. This output is high impedance when CS is high.  
Data In. Logic input. Data to be written to the AD78ꢀ3 control register is provided on this input and is clocked into  
the register on the rising edge of DCLK (see the Control Register section).

CS  
Chip Select Input. Active Low Logic Input. This input provides the dual function of initiating conversions on the  
AD78ꢀ3 and also enables the serial input/output register.  
External Clock Input. Logic Input. DCLK provides the serial clock for accessing data from the part. This clock input  
is also used as the clock source for the AD78ꢀ3 conversion process.
