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.
