TLV2543CDB 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, it's recommended to use a low-ESR capacitor for the AVCC pin and to keep the input traces as short as possible.
  • The TLV2543CDB has a built-in POR and BOR circuitry, but it's recommended to add an external reset circuit to ensure a clean power-up sequence. This can be done using a voltage supervisor IC or a simple RC circuit.
  • The TLV2543CDB can sample at up to 400 kHz, but this depends on the clock frequency and the conversion mode. In fast conversion mode, the maximum sampling rate is around 200 kHz, while in low-power mode, it's around 10 kHz.
  • The TLV2543CDB has a built-in calibration circuit, but it's recommended to perform a system-level calibration to account for external factors such as temperature and voltage variations. This can be done using a calibration routine that writes the calibration data to the device's registers.
  • The TLV2543CDB is specified to operate from -40°C to 125°C, but it's recommended to operate within the -20°C to 85°C range for optimal performance and accuracy.
