A good PCB layout for the TDC1011QPWRQ1 involves keeping the analog and digital grounds separate, using a solid ground plane, and placing the device close to the analog power supply. Additionally, it's recommended to use a 4-layer PCB with a dedicated layer for the analog power supply and another for the digital power supply.
To ensure proper calibration, follow the calibration procedure outlined in the datasheet, which involves applying a known input voltage and adjusting the internal calibration registers. It's also important to ensure the device is operated within the recommended temperature range and that the input signal is within the specified range.
The recommended input signal conditioning for the TDC1011QPWRQ1 involves using a low-pass filter to remove high-frequency noise and a voltage divider or attenuator to adjust the input signal to within the specified range. Additionally, it's recommended to use a buffer amplifier to isolate the input signal from the device.
To troubleshoot issues with the TDC1011QPWRQ1, start by verifying the input signal is within the specified range and that the device is properly calibrated. Check the PCB layout for any noise or interference issues and ensure the device is operated within the recommended temperature range. If issues persist, consult the datasheet and application notes for troubleshooting guides or contact Texas Instruments support.
The TDC1011QPWRQ1 has a recommended operating temperature range of -40°C to 125°C. To ensure the device operates within this range, ensure good thermal conductivity between the device and the PCB, use a heat sink if necessary, and avoid exposing the device to extreme temperatures during storage or operation.
