Reference Buffer Output/ADC Reference Input. Reference voltage for analog-to-digital conversion. In
internal reference mode, the reference buffer provides a +4.096V nominal output, externally adjustable at
REFADJ. In external reference mode, disable the internal buffer by pulling REFADJ to AV
AGND with a 2.2µF capacitor when using the internal reference.
Bandgap Reference Output/Bandgap Reference Buffer Input. Bypass to AGND with 0.22µF. When using an
external reference, connect REFADJ to AV
Analog Ground. This is the primary analog ground (Star Ground).
Analog Supply. 5V ±5%. Bypass AV
Digital Ground
Shutdown Control Input. Drive SHDN low to put the ADC in shutdown mode.

Serial Strobe Output. In internal clock mode, SSTRB goes low when the ADC begins a conversion and goes
high when the conversion is finished. In external clock mode, SSTRB pulses high for one clock period
before the MSB decision. It is high impedance when CS is high in external clock mode.
Serial Data Output. MSB first, straight binary format for unipolar input, two’s complement for bipolar input.
Each bit is clocked out of DOUT at the falling edge of SCLK.
