The ADS1120QPWRQ1 requires careful layout and placement to minimize noise and ensure accurate conversions. TI recommends placing the device close to the analog signal sources, using a solid ground plane, and keeping digital and analog traces separate. Additionally, decoupling capacitors should be placed close to the device's power pins.
To optimize the ADS1120QPWRQ1's performance, consider the following: choose the correct gain setting, adjust the sampling rate, and select the appropriate clock source. Additionally, ensure proper filtering and signal conditioning of the input signal, and consider using the device's built-in calibration features.
The ADS1120QPWRQ1 is specified to operate up to 125°C. However, high temperatures can affect the device's accuracy and noise performance. Ensure proper thermal management, and consider using thermal shielding or heat sinks if operating in high-temperature environments.
To ensure EMC, follow proper PCB design practices, such as using a solid ground plane, minimizing loop areas, and using shielding. Additionally, consider using common-mode filters and ferrite beads to reduce electromagnetic interference (EMI).
The ADS1120QPWRQ1 requires proper power sequencing to prevent damage or incorrect operation. Ensure that the analog power supply (AVDD) is powered up before the digital power supply (DVDD), and that the clock signal is stable before starting conversions.
