ADS114S08IRHBT Frequently Asked Questions (FAQs)

  • 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 ADS114S08'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 offset calibration register to adjust the offset voltage to your specific application's requirements.
  • Power up the device in the following sequence: AVDD, DVDD, and then the analog input voltage. Ensure that the power supplies are stable and within the recommended operating range before applying the analog input voltage.
  • Use the Power-Down (PD) pin to put the device in power-down mode. In this mode, the device consumes minimal power. You can also use the SPI interface to put the device in standby mode, which reduces power consumption while still allowing the device to respond to SPI commands.
  • Use an anti-aliasing filter (AAF) with a cutoff frequency set to less than half the sampling frequency to minimize aliasing. A 2nd-order or 4th-order Butterworth filter is recommended. Additionally, use a low-pass filter to remove high-frequency noise from the analog input signal.
