TAS3108IADCPR datasheet by Texas Instruments

TAS3108IADCPR Frequently Asked Questions (FAQs)

• What is the recommended power-up sequence for the TAS3108?
  The recommended power-up sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper device operation and prevents damage.
• How do I optimize the TAS3108's analog-to-digital converter (ADC) performance?
  To optimize ADC performance, ensure proper analog input signal conditioning, use a low-noise power supply, and minimize digital noise coupling to the analog inputs. Additionally, adjust the ADC clock frequency and sampling rate according to the application's requirements.
• What is the maximum allowed capacitance on the analog input pins?
  The maximum allowed capacitance on the analog input pins is 10nF. Exceeding this value may affect the device's performance and stability.
• Can I use the TAS3108 with a separate analog ground plane?
  Yes, a separate analog ground plane can be used, but it must be connected to the digital ground plane at a single point, typically near the power supply. This helps to minimize noise coupling between the analog and digital sections.
• How do I handle the TAS3108's digital output data format?
  The TAS3108's digital output data is in 2's complement format. Ensure that the receiving device or microcontroller is configured to handle this format correctly to avoid data corruption or misinterpretation.
