Design Notes
Decouple the AVDD and DVDD pins with 10 Β΅F and 0.1 Β΅F capacitors placed close to the pins. Use separate analog and digital ground planes to minimize noise coupling. The AD7175-2 operates from 2 V to 5.5 V supplies; ensure the analog and digital supplies are within specification and properly filtered.
For optimal performance, place the ADC close to the sensor and use a low-noise reference like the ADR445. Route analog inputs away from digital traces to reduce interference. Use a solid ground plane under the ADC and keep the SPI lines short and shielded if necessary.
Avoid exceeding the absolute maximum ratings on the analog inputs. Ensure the reference voltage is stable and within the specified range. The SPI interface should be configured correctly; incorrect timing can cause communication errors. Also, note that the AD7175-2 requires an external reference; do not operate without one.
