TLC2543IDWG4 datasheet by Texas Instruments

TLC2543IDWG4 Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC2543?
  The recommended power-on sequence is to apply VCC first, followed by VREF, and then the analog input signal. This ensures proper operation and prevents latch-up.
• How do I handle the output data format of the TLC2543?
  The TLC2543 outputs data in a 3-wire serial format. The output data is clocked out on the SDO pin on the falling edge of the clock signal (SCK). The output data is valid on the rising edge of SCK.
• What is the maximum sampling rate of the TLC2543?
  The maximum sampling rate of the TLC2543 is 400 kHz. However, the actual sampling rate may be limited by the system clock frequency and the conversion time.
• How do I calibrate the TLC2543?
  The TLC2543 does not require calibration. It has an internal calibration circuit that ensures accurate conversions. However, the user may need to adjust the reference voltage (VREF) to match the desired full-scale input range.
• What is the effect of clock jitter on the TLC2543's performance?
  Clock jitter can affect the TLC2543's performance by introducing noise and reducing the signal-to-noise ratio (SNR). It is recommended to use a low-jitter clock source to ensure optimal performance.
