TLC5620CD datasheet by Texas Instruments

TLC5620CD Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC5620CD?
  The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper device operation and prevents latch-up.
• How do I ensure accurate conversions with the TLC5620CD?
  To ensure accurate conversions, it's essential to provide a stable and noise-free analog input signal, use a high-quality reference voltage, and minimize digital noise coupling into the analog circuitry.
• What is the maximum clock frequency for the TLC5620CD?
  The maximum clock frequency for the TLC5620CD is 20 MHz. Exceeding this frequency may result in incorrect conversions or device malfunction.
• Can I use the TLC5620CD in a multiplexed system?
  Yes, the TLC5620CD can be used in a multiplexed system. However, it's essential to ensure that the multiplexer is properly synchronized with the ADC's conversion cycle to avoid errors.
• How do I handle overvoltage conditions on the analog input?
  To handle overvoltage conditions, use a voltage limiter or a clamp circuit to prevent the analog input signal from exceeding the maximum rated voltage of the TLC5620CD.
