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 TLV2543IDBR has a built-in POR and BOR circuitry that resets the device during power-up or brown-out conditions. To handle this, ensure that your system design can tolerate the reset pulse duration and that your firmware is designed to handle the reset sequence.
The TLV2543IDBR can achieve a maximum sampling rate of 400 kSPS, but this may vary depending on the specific configuration and operating conditions. It's recommended to consult the datasheet and application notes for more information.
The TLV2543IDBR has a built-in calibration circuitry, but it may require additional calibration steps depending on the specific application. Texas Instruments recommends following the calibration procedure outlined in the datasheet and application notes.
The TLV2543IDBR is specified to operate from -40°C to 125°C, but it's recommended to consult the datasheet and reliability reports for more information on the device's operating temperature range and thermal considerations.
