The AD7175-2BRUZ is a Low Power 24-bit 250kSPS Sigma-Delta (Σ-Δ) ADC with 20μs settling and true rail to rail buffers for low bandwidth input. It has a maximum channel scan rate of 50kSPS (20μs) for fully settled data. The output data rates range from 5SPS to 250kSPS. The AD7175-2 integrates key analogue and digital signal conditioning blocks to allow users to configure an individual setup for each analogue input channel in use. Each feature can be user selected on a per channel basis. Integrated true rail to rail buffers on the analogue inputs and external reference inputs provide easy to drive high impedance inputs. The precision 2.5V low drift (2ppm/°C) band gap internal reference (with output reference buffer) adds embedded functionality to reduce external component count. The digital filter allows simultaneous 50/60Hz rejection at 27.27SPS output data rate. The user can switch between different filter options according to the demands of each channel in the application.
