I/O/Z Digital input, output (D11 = MSB). The data line D11 is also used as an address line (RA1) for the control register.  
This is required for writing to control register 0 and control register 1. See Table 7.  
I
Common-modereference input for the analog input channels. It is recommended that this pin be connected to the  
reference output REFOUT.  
REFP  
I
Reference input, requires a bypass capacitor of 10 µF to AGND in order to bypass the internal reference voltage.  
An external reference voltage at this input can be applied. This option can be programmed through control  
register 0. See Table 8.

I
Analog fixed reference output voltage of 2.5 V. Sink and source capability of 250 µA. The reference output  
requires a capacitor of 10 µF to AGND for filtering and stability.

RD  
The RD input is used only if the WR input is configured as a write only input. In this case, it is a digital input, active  
low as a data read select from the processor. See timing section.  
SYNC  
O
I
Synchronizationoutput. This signal indicates in a multichannel operation that data of channel A is brought to the  
digital output and can therefore be used for synchronization.  
(1)  
WR (R/W)  
This input is programmable. It functions as a read-write input R/W and can also be configured as a write-only  
input WR, which is active low and used as data write select from the processor. In this case, the RD input is used  
as a read input from the processor. See timing section.  
(1)  
The start-conditions of RD and WR (R/W) are unknown. The first access to the ADC has to be a write access to initialize the ADC.
