1. Describe
The AD7177-2BRUZ is a 32-bit low noise, fast settling, multiplexed, 2-channel/4-channel (full/pseudo-differential) sigma-delta analog-to-digital converter (ADC) for low bandwidth inputs. It has a maximum channel scan rate of 10 kSPS (100 µs) for fully stable data. Output data rates range from 5 SPS to 10 kSPS. The AD7177-2 integrates key analog and digital signal conditioning blocks, allowing the user to configure individual settings for each analog input channel in use. Users can select each function on a per channel basis. True rail-to-rail buffers integrated on the analog inputs and external reference inputs provide easy-to-drive, high-impedance inputs. A precision 2.5 V low drift (2 ppm/°C) bandgap internal reference with output reference buffer adds embedded functionality to reduce external component count. A digital filter allows simultaneous rejection of 50 Hz and 60 Hz at an output data rate of 27.27 SPS. Users can switch between different filter options based on the needs of each channel in the application. The ADC automatically switches each selected channel. Further digital processing functions include offset and gain calibration registers, configurable on a per-channel basis. The device operates from a 5 V AVDD1 supply or ±2.5 V AVDD1/AVSS and a 2 V to 5 V AVDD2 and IOVDD supply. The specified operating temperature range is -40°C to +105°C. The AD7177-2 is available in a 24-lead TSSOP package.
