GND  
External Reference Voltage Input. Sets the analog voltage range.  
Note: Bypass with a 4.7µF capacitor to GND.  
5
REF  
Conversion Start. A rising edge powers up the device and puts the track/  
hold circuitry in track mode. At the falling edge of this pin, the device enters  
hold mode and begins a conversion.  
6
CNVST  
Note: This pin also selects the input channel (AS1529) or input polarity  
(AS1528).  
Serial Data Output. This pin transitions the falling edge of SCLK and goes  
low at the start of a conversion and delivers the MSB at the completion of a  
conversion.

DOUT  
SCLK  
Note: This pin goes high impedance once data has been fully clocked out.  
Serial Clock Input. Clocks out data at DOUT with the MSB first.
