TLC352CDR datasheet by Texas Instruments

TLC352CDR Frequently Asked Questions (FAQs)

• What is the recommended power-on sequence for the TLC352CDR?
  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 damage to the device.
• How do I ensure accurate conversion results with the TLC352CDR?
  To ensure accurate conversion results, it is essential to follow proper PCB layout guidelines, use a low-noise power supply, and minimize noise coupling into the analog input signal. Additionally, ensure that the reference voltage (VREF) is stable and accurate.
• What is the maximum clock frequency that can be used with the TLC352CDR?
  The maximum clock frequency for the TLC352CDR is 20 MHz. Exceeding this frequency may result in inaccurate conversion results or device malfunction.
• Can I use the TLC352CDR in a multiplexed configuration?
  Yes, the TLC352CDR can be used in a multiplexed configuration. However, it is 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 of the TLC352CDR?
  To handle overvoltage conditions, it is recommended to use external protection circuitry, such as a voltage clamp or a resistive divider, to limit the input voltage to within the specified range of the TLC352CDR.
