TLV1543CDBR Frequently Asked Questions (FAQs)

  • Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital traces separate. Additionally, use a low-ESR capacitor for the VCC pin and a 0.1uF capacitor for the REF pin. Route the input traces as close to the IC as possible and avoid crossing digital traces over the analog traces.
  • The TLV1543CDBR has a built-in POR and BOR circuitry. To handle POR, ensure that the VCC pin is ramped up slowly (>10ms) to avoid false triggers. For BOR, connect a capacitor (typically 10nF) between the VCC pin and the BOR pin to filter out noise and glitches.
  • The recommended clock frequency for the TLV1543CDBR is between 1.5MHz and 4MHz. A higher clock frequency can increase the conversion rate, but it also increases the power consumption and noise sensitivity. A typical conversion rate is around 10ksps at 2MHz clock frequency.
  • The TLV1543CDBR has a built-in calibration circuitry. To calibrate, apply a known input voltage to the input pins and read the output code. Then, adjust the offset and gain trim bits to achieve the desired accuracy. It's recommended to perform calibration at multiple temperatures and input voltages to ensure optimal performance.
  • The maximum input voltage range for the TLV1543CDBR is ±VREF (typically ±2.5V). Exceeding this range can cause non-linearity and accuracy issues. To maintain linearity and accuracy, ensure that the input voltage is within the specified range and use an input buffer or attenuator if necessary.
