TLV2543CDWR 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 decouple the VCC pin with a 0.1uF capacitor.
  • The POR and BOR features are enabled by default, but can be disabled by tying the POR/BOR pin to VCC. It's recommended to use an external reset circuit or a supervisor IC to ensure a clean power-on reset and to handle brown-out conditions.
  • The maximum sampling rate of the TLV2543CDWR is 400 kHz, and it affects the power consumption significantly. At higher sampling rates, the power consumption increases, so it's recommended to use the lowest sampling rate required for the application to minimize power consumption.
  • The TLV2543CDWR has a built-in calibration feature that can be accessed through the CAL pin. Texas Instruments recommends a two-point calibration procedure, where the device is calibrated at two known input voltages to ensure accurate readings across the entire input range.
  • The TLV2543CDWR has a specified temperature range of -40°C to 125°C, and the accuracy and linearity can be affected by temperature variations. Texas Instruments recommends using temperature compensation techniques, such as using a temperature sensor and adjusting the readings accordingly, to ensure accurate readings across the entire temperature range.
