ADS8504IBDW 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 power supply with 0.1uF and 10uF capacitors.
  • The ADS8504IBDW outputs 16-bit data in two's complement format. The default format is MSB-first, but this can be changed to LSB-first by setting the MSB/LSB pin high. The output data can be accessed through the SPI-compatible interface.
  • The maximum sampling rate of the ADS8504IBDW is 200 kSPS. The power consumption increases with the sampling rate, but the device can operate at a lower power consumption mode by reducing the sampling rate. The power consumption can be reduced by up to 50% at lower sampling rates.
  • The ADS8504IBDW has an internal calibration circuit that can be enabled by setting the CAL pin high. Calibration is recommended to ensure accurate measurements, especially in high-precision applications. The calibration process takes approximately 100 ms and can be performed during power-up or during normal operation.
  • The input voltage range of the ADS8504IBDW is ±2.5 V. The accuracy of the measurements is affected by the input voltage range, with higher accuracy at lower input voltages. The device can operate with input voltages up to ±5 V, but the accuracy may be compromised.
