- Higher sampling rate than ADS7066 (vs ADS7066)
Design Notes
Decouple the AVDD and DVDD supplies with 0.1uF and 1uF capacitors placed as close to the pins as possible. The analog and digital supplies should be separated to minimize noise coupling. Use a low-noise LDO for the analog supply to maintain SNR.
The integrated capless reference requires no external capacitor, but bypass the REF pin with a 0.1uF capacitor to ground for optimal performance. Keep analog input traces short and shielded to reduce noise pickup. Use a solid ground plane under the device.
Ensure the input voltage does not exceed the specified range. The PGA can be configured for ±VREF to ±12VREF, but verify the absolute maximum ratings. Avoid floating GPIO pins; configure them as inputs or outputs in the control register to prevent undefined states.
