Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals, and avoid crossing digital signals over analog signals. Also, decouple the AVDD and DVDD pins with 0.1uF capacitors.
Use the ADS114S06's built-in calibration modes to optimize gain and offset. The device has a self-calibration mode that can be triggered through the SPI interface. Additionally, you can use the device's internal offset calibration register to adjust the offset voltage.
Power up the device in the following sequence: AVDD, DVDD, and then the digital interface (e.g., SPI or I2C). Ensure that the power supplies are stable and within the recommended voltage range before applying the digital interface signals.
Use the device's power-down mode by setting the PDWN pin low. In this mode, the device's analog and digital circuits are powered down, reducing power consumption. You can also use the SPI interface to control the power-down mode.
The recommended clock frequency for the SPI interface is up to 10 MHz. However, the device can operate at higher frequencies, but this may require additional signal integrity considerations.
