ADS831E/2K5 Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. Additionally, it's recommended to use a low-ESR capacitor for the AVDD pin and to keep the input traces as short as possible.
  • The ADS831E/2K5 has an internal calibration circuit that can be used to calibrate the device. The calibration process involves applying a known input voltage and then reading the output code. The device can then be calibrated by adjusting the internal offset and gain registers.
  • The maximum sampling rate of the ADS831E/2K5 is 100 kSPS. However, the actual sampling rate may be limited by the system clock frequency, the conversion time, and the settling time of the input signal.
  • The ADS831E/2K5 outputs 16-bit data in a binary two's complement format. The output data can be read through the SPI interface, and the device can be configured to output the data in either MSB-first or LSB-first format.
  • The power consumption of the ADS831E/2K5 is typically around 15 mW at a supply voltage of 2.7 V. The power consumption can be reduced by reducing the supply voltage, reducing the sampling rate, or by using the device's power-down mode.
