ADS8028IRTJR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. The analog input traces should be routed close to the AGND plane, and the digital output traces should be routed away from the analog input traces. Additionally, decoupling capacitors should be placed close to the device.
  • The ADS8028IRTJR outputs 16-bit data in two's complement format. The recommended data processing flow is to perform a digital low-pass filter to remove high-frequency noise, followed by a gain and offset correction to adjust the output to the desired range.
  • The recommended power-up sequence is to apply the analog power supply (AVDD) first, followed by the digital power supply (DVDD). During power-down, the sequence should be reversed. Additionally, the digital interface should be inactive during power-up and power-down to prevent incorrect operation.
  • The ADS8028IRTJR has an internal calibration circuit that can be used to adjust the gain and offset of the device. The calibration process involves applying a known input voltage and adjusting the internal calibration registers to achieve the desired output code. The calibration process should be performed at the operating temperature range of the device.
  • The ADS8028IRTJR has a SYNC input pin that can be used to synchronize the device with an external clock or trigger signal. The SYNC pin should be driven with a digital signal that meets the device's input requirements, and the device should be configured to use the external clock or trigger signal as the sampling clock.
