A good layout and routing practice is to keep the analog and digital grounds separate, use a solid ground plane, and keep the analog and digital signals separate. Additionally, use a low-ESR capacitor for the VCC pin and a 0.1uF capacitor for the REFIN pin.
To ensure accuracy, use a high-quality external reference voltage, ensure the input signal is within the specified range, and use the correct gain and offset calibration. Additionally, consider using a low-noise, low-temperature-coefficient voltage reference.
The recommended power-up sequence is to apply VCC first, followed by the reference voltage (REFIN), and then the analog input signals. This ensures that the internal bias circuits are properly initialized.
The LTC2355IMSE-14#PBF has a maximum junction temperature of 150°C. To ensure reliable operation, ensure good airflow, use a heat sink if necessary, and avoid operating the device near its maximum temperature rating.
Use a low-impedance source, such as an op-amp buffer, to drive the analog input signals. This ensures that the input signals are not distorted or attenuated, and that the ADC can accurately convert the input signals.
