The AD7177-2 is a 32-bit low noise, fast settling, multiplexed,2-/4-channel (fully/pseudo differential) Σ-Δ analog-to-digitalconverter (ADC) for low bandwidth inputs. It has a maximumchannel scan rate of 10 kSPS (100 µs) for fully settled data. Theoutput data rates range from 5 SPS to 10 kSPS.The AD7177-2 integrates key analog and digital signal conditioningblocks to allow users to configure an individual setup foreach analog input channel in use. Each feature can be user selectedon a per channel basis. Integrated true rail-to-rail buffers on theanalog inputs and external reference inputs provide easy to drivehigh impedance inputs. The precision 2.5 V low drift (2 ppm/°C)band gap internal reference (with output reference buffer) addsembedded functionality to reduce external component 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 eachchannel in the application. The ADC automatically switchesthrough each selected channel. Further digital processingfunctions include offset and gain calibration registers,configurable on a per channel basis.The device operates with a 5 V AVDD1 supply, or with ±2.5 VAVDD1/AVSS, and 2 V to 5 V AVDD2 and IOVDD supplies.The specified operating temperature range is −40°C to +105°C.The AD7177-2 is available in a 24-lead TSSOP package.
