Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to route the analog and digital signals separately to minimize noise and interference. Additionally, it's recommended to use a common mode filter and a ferrite bead to filter out high-frequency noise.
To optimize the ADC's performance, it's essential to understand the application's requirements and adjust the ADC's settings accordingly. This includes selecting the appropriate gain, data rate, and filter settings. Additionally, ensuring a clean and stable power supply, and minimizing noise and interference in the system can also improve performance.
The recommended power-up sequence is to first apply the analog power supply (AVDD), followed by the digital power supply (DVDD), and then the clock signal. This ensures that the ADC is properly initialized and configured before starting conversions.
The ADS122C04IRTET has a latency of 2-3 clock cycles, depending on the mode of operation. To ensure accurate conversions, it's essential to ensure that the input signal is stable and settled before starting a conversion. Additionally, using the ADC's built-in latency compensation feature can help minimize the effects of latency.
The ADS122C04IRTET has a built-in calibration feature that can be used to calibrate the ADC. The recommended method is to perform a system calibration, which involves applying a known input voltage and adjusting the ADC's offset and gain settings to achieve optimal performance.
