TThe AD7172-2 is an intelligent, low noise, low power, multiplexed,Σ-Δ analog-to-digital converter (ADC) with 2- or 4-channel(fully differential/single-ended) inputs for low bandwidthsignals. The AD7172-2 has a maximum channel scan rate of6.21 kSPS (161 µs) for fully settled data. The output data ratesrange from 1.25 SPS to 31.25 kSPS.The AD7172-2 integrates key analog and digital signal conditioningblocks to allow users to configure an individual setup for eachanalog input channel in use via the SPI. Integrated true rail-to-railbuffers on the analog inputs and external reference inputs provideeasy to drive high impedance inputs. The precision 2.5 V low drift(2 ppm/°C) band gap internal reference (with an output referencebuffer) adds embedded functionality to reduce the externalcomponent count.The digital filter allows simultaneous 50 Hz and 60 Hz rejectionat a 27.27 SPS output data rate. The user can switch betweendifferent filter options according to the demands of each channel inthe application, with further digital processing functions such asoffset and gain calibration registers, which are also configurable ona per channel basis. General-purpose inputs/outputs (GPIOs)control external multiplexers synchronous to the ADC conversiontiming.The specified operating temperature range is −40°C to +105°C.The AD7172-2 is in a 24-lead TSSOP package.
