TLC5628CN datasheet by Texas Instruments

TLC5628CN Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC5628CN?
  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 potential latch-up.
• How do I ensure accurate conversions with the TLC5628CN?
  To ensure accurate conversions, it's essential to provide a stable and noise-free power supply, use a high-quality reference voltage, and minimize noise on the analog input signal. Additionally, ensure the device is operated within its specified temperature range.
• What is the maximum clock frequency for the TLC5628CN?
  The maximum clock frequency for the TLC5628CN is 20 MHz. Exceeding this frequency may result in inaccurate conversions or device malfunction.
• Can I use the TLC5628CN in a multiplexed system?
  Yes, the TLC5628CN can be used in a multiplexed system. However, it's essential to ensure that the device is properly reset between conversions, and the analog input signal is properly switched to prevent signal degradation.
• How do I handle overvoltage conditions on the analog input of the TLC5628CN?
  To handle overvoltage conditions, use external protection circuitry, such as a voltage clamp or a resistive divider, to limit the analog input voltage to within the specified range of 0 to VREF.
