The AD7172-2BRUZ is a 2/4-channel intelligent low noise, low power multiplexed sigma-delta Analog-to-digital Converter (ADC) with true rail-to-rail buffers. The converter has a maximum channel scan rate of 6.21kSPS for fully settled data. The output data rates range from 1.25SPS to 31.25kSPS. It integrates key analog and digital signal conditioning blocks to allow users to configure an individual setup for each analog input channel in use via the SPI. Integrated true rail-to-rail buffers on the analog inputs and external reference inputs provide easy to drive high impedance inputs. The precision 2.5V low drift band gap internal reference adds embedded functionality to reduce the external component count. The user can switch between different filter options according to the demands of each channel in the application with further digital processing functions such as offset and gain calibration registers which are also configurable on a per channel basis.
