TLC1549CD datasheet by Texas Instruments

TLC1549CD Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC1549CD?
  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 to prevent overvoltage damage?
  Use external resistors or voltage dividers to limit the analog input voltage to within the specified range (0 to VCC). Also, consider adding input protection diodes or voltage clamps to prevent overvoltage damage.
• What is the maximum sampling rate I can achieve with the TLC1549CD?
  The maximum sampling rate depends on the clock frequency and the conversion mode. In the fastest mode, the TLC1549CD can achieve a sampling rate of up to 65,536 samples per second.
• How do I calibrate the TLC1549CD to achieve optimal performance?
  Perform a self-calibration procedure by applying a known input voltage and adjusting the internal offset and gain registers to achieve optimal linearity and accuracy.
• Can I use the TLC1549CD in a multiplexed configuration?
  Yes, the TLC1549CD can be used in a multiplexed configuration by connecting multiple analog input channels to the ADC inputs and using the channel select inputs to select the desired channel.
