The AD7172-4 is a low noise, low power, multiplexed, Σ-Δ analog-to-digital converter (ADC) with 4- or 8-channel (fully differential/single-ended) inputs for low bandwidth signals. The AD7172-4 has a maximum channel scan rate of 6.21 kSPS (161 μs) for fully settled data. The output data rates range from 1.25 SPS to 31.25 kSPS.The AD7172-4 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 reference inputs provide easy to drive high impedance inputs.The digital filter allows simultaneous 50 Hz and 60 Hz rejection at a 27.27 SPS output data rate. 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 configurable on a per channel basis. General-purpose input/outputs (GPIOs) control external multiplexers synchronous to the ADC conversion timing. The specified temperature range is −40°C to +105°C.The AD7172-4 is in a 5 mm × 5 mm, 32-lead LFCSP.Note that, throughout this data sheet, the dual function pinnames are referenced by the relevant function only.
