1 pcs : AD7172-2BRUZ - Analog to Digital Converters - ADC Low Power, 24-Bit, 31.25 kSPS, Sigma-Delta ADC with True Rail-to-Rail

AD7172-2 24-Bit Sigma-Delta ADC Analog Devices AD7172-2 24-Bit Sigma-Delta ADC is an intelligent, low noise, low power, multiplexed, sigma-delta analog-to-digital converter with 2- or 4-channel (fully differential/single-ended) inputs for low bandwidth signals. ADI AD7172-2 has a maximum channel scan rate of 6.21kSPS (161μs) for fully settled data. The output data rates range from 1.25SPS to 31.25kSPS. AD7172-2 integrates key analog and digital signal conditioning blocks to allow users to configure an individual setup for each analog input channel in use via SPI. Integrated true rail-to-rail buffers on the analog inputs and external reference inputs provide easy to drive high impedance inputs. The precision 2.5V low drift (f2 ppm/°C) band gap internal reference (with an output reference buffer) adds embedded functionality to reduce external component count. The digital filter allows simultaneous 50Hz/60Hz rejection at a 27.27SPS 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 also configurable on a per channel basis. General-purpose inputs/outputs (GPIOs) can control external multiplexers synchronous to ADC conversion timing. The specified operating temperature range is −40°C to +105°C. AD7172-2 is in a 24-lead TSSOP package.Learn More
