The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signal. This ensures proper operation and prevents damage to the device.
To minimize noise and interference, keep the analog and digital grounds separate, use a solid ground plane, and keep the analog input traces away from digital traces. Also, use a low-pass filter on the analog input to reduce high-frequency noise.
The maximum sampling rate of the ADS8320EB/250 is 250 kSPS. However, the actual sampling rate may be limited by the system's clock frequency, analog input bandwidth, and other factors.
The ADS8320EB/250 outputs 16-bit data in two's complement format. The most significant bit (MSB) is the sign bit, and the remaining 15 bits represent the magnitude of the signal. You can use a microcontroller or FPGA to process and convert the data to a desired format.
The recommended operating temperature range for the ADS8320EB/250 is -40°C to 85°C. Operating the device outside this range may affect its performance and reliability.
