The AD7172-4 ADCs integrate key analog and digital signal conditioning blocks to allow designers 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. AD7172-4's digital filter enables simultaneous 50Hz and 60Hz rejection at a 27.27SPS output data rate. The designer can switch between different filter options according to the demands of each channel in the application. Additional digital processing functions such as offset and gain calibration registers are configurable on a per-channel basis. General-purpose input/outputs (GPIOs) control external multiplexers synchronous to the ADC conversion timing.
Available in a 5mm × 5mm, 32-lead LFCSP package and specified for an operating temperature range of 40°C to +105°C, the AD7172-4 ADCs are well-suited for PLC/DCS modules for process control, temperature & pressure measurement, medical & scientific multi-channel instrumentation, and chromatography.
Analog Devices offers the EVAL-AD7172-4SDZ evaluation kit to help designers evaluate the features of the AD7172-4 ADC.
