  • Product Details:

    The AD7172-4 is a low-noise, low-power, multiplexed sigma-delta analog-to-digital converter (ADC) with 4/8 channels (fully differential/single-ended) inputs for low-bandwidth signals. The AD7172-4 has a maximum channel scan rate of 6.21 kSPS (161 μs) for fully established data. The device has an output data rate range of 1.25 SPS to 31.25 kSPS.

    The AD7172-4 integrates key analog and digital signal conditioning modules, allowing users to individually configure each active analog input channel via SPI. Integrated true rail-to-rail buffers at analog and reference inputs provide easy-to-drive high-impedance inputs.

    The digital filter allows for simultaneous rejection of 50 Hz and 60 Hz at 27.27 SPS output data rate. Users can switch between different filter options depending on the needs of each channel in the application, and further digital processing functions such as offset and gain calibration registers can be configured on a per-channel basis. Universal input/output (GPIO) controls external multiplexers and synchronizes them to the ADC conversion timing. The AD7172-4 is rated for an operating temperature range of −40°C to +105°C. Available in 5 mm × 5 mm, 32-pin LFCSP packages.

    Note that throughout the datasheet, the dual function pin name is only referenced by the relevant function.
