Texas Instruments recommends a 4-layer PCB with a solid ground plane, and placing the ADS1202IPWR close to the analog signal sources to minimize noise. Additionally, it's recommended to use a separate analog ground plane and to keep digital signals away from the analog signals.
To optimize performance in a noisy environment, use a low-pass filter on the analog input, use a shielded cable for the analog input, and consider using a common-mode filter. Additionally, ensure that the power supply is clean and well-regulated, and consider using a separate analog power supply.
The maximum sampling rate of the ADS1202IPWR is 15,000 samples per second (SPS) for a single channel, and 7,500 SPS for dual-channel mode. However, the actual sampling rate may be limited by the system's clock frequency and the conversion time.
The ADS1202IPWR outputs 24-bit data in a serial format. The data can be read using a microcontroller or FPGA, and can be processed using a digital signal processor or a microcontroller. It's recommended to use a FIFO buffer to handle the data and to ensure that the data is read at the correct rate.
The power consumption of the ADS1202IPWR is typically around 15mW at 3V supply voltage, but can vary depending on the operating frequency, sampling rate, and other factors. It's recommended to consult the datasheet and to perform power consumption measurements in the actual application.
