programming the ADC into the desired mode. The  
THS1009 consists of two analog inputs, which are  
sampled simultaneously. These inputs can be selected  
individually and configured to single-ended or  
differential inputs. Internal reference voltages for the  
ADC (1.5 V and 3.5 V) are provided. An external  
reference can also be chosen to suit the dc accuracy  
and temperature drift requirements of the application.
