A good layout and routing practice is to keep the analog and digital grounds separate, use a star-ground configuration, and keep the sensitive analog signals away from the digital signals. Additionally, use a low-ESR capacitor for the VREF pin and keep the input and output traces short and direct.
The TLV5614IDR is specified to operate from -40°C to 125°C. Ensure good airflow around the device, avoid overheating, and use a heat sink if necessary. Monitor the device's junction temperature (TJ) and ensure it stays within the specified range.
The recommended power-up sequence is to apply VCC first, followed by VREF, and then the input signals. This ensures that the internal voltage regulators are stable before the analog-to-digital conversion begins.
The TLV5614IDR outputs 14-bit data in a binary two's complement format. Ensure that your microcontroller or digital system can handle this format, and consider using a FIFO or buffer to handle the data transfer.
The TLV5614IDR has an internal calibration circuit. Apply a known input voltage, and then use the CAL pin to initiate the calibration process. The device will adjust its internal offset and gain to ensure accurate conversions.
