TLC1549CP datasheet by Texas Instruments

TLC1549CP Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC1549CP?
  The recommended power-on sequence is to apply VCC first, followed by AVCC, and then the analog input signals. This ensures proper internal biasing and prevents latch-up.
• How do I handle the analog input signals when the TLC1549CP is in power-down mode?
  When the TLC1549CP is in power-down mode, the analog input signals should be disconnected or held at a stable voltage to prevent unwanted current consumption and noise.
• What is the maximum capacitance allowed on the analog input pins?
  The maximum capacitance allowed on the analog input pins is 10nF. Exceeding this value may affect the ADC's performance and accuracy.
• Can I use the TLC1549CP in a system with multiple ADCs?
  Yes, the TLC1549CP can be used in a system with multiple ADCs, but ensure that each ADC has its own separate analog ground and that the analog grounds are not connected to the digital ground.
• How do I minimize noise and interference when using the TLC1549CP?
  To minimize noise and interference, use a low-pass filter on the analog input signals, keep the analog and digital grounds separate, and use a decoupling capacitor on the AVCC pin.
