A/D-Converter

The IP200 contains two integrated Analogue Digital Converter with a maximum sample rate of 1.25MS/s. In

some special applications, were the analogue sensor signal do not match the analogue front end (AFE)

inputs, bypassing the AFE. In this case, the conditioned sensor signals must be sine shaped with a

reference voltage circuit that generates the V0 with a nominal voltage of 2.375V.
