The datasheet provides some general guidelines, but a good rule of thumb is to keep the analog and digital grounds separate, use a solid ground plane, and place the device close to the analog signal sources. Additionally, use a low-ESR capacitor for the VCC pin and keep the PCB traces as short as possible to minimize noise.
Use a buffer amplifier or an op-amp with a high input impedance (>10GΩ) to drive the analog input pins. This will help to prevent signal attenuation and ensure accurate readings. Additionally, use a low-capacitance cable or PCB trace to connect the signal source to the input pins.
The maximum sampling rate of the LTC2480IMS#PBF is 15ksps. However, the power consumption increases with the sampling rate. At the maximum sampling rate, the power consumption is around 10mA. To reduce power consumption, consider using a lower sampling rate or enabling the device's power-down mode when not in use.
The LTC2480IMS#PBF has an internal calibration circuit that can be enabled by setting the CAL pin high. During calibration, the device measures its internal voltage reference and adjusts its gain and offset to ensure accurate readings. It's recommended to perform calibration after power-up and whenever the device is reset.
The LTC2480IMS#PBF has a specified operating temperature range of -40°C to 125°C. Temperature changes can affect the device's accuracy and performance, particularly the voltage reference and analog-to-digital converter. To minimize temperature-related errors, consider using a temperature sensor to monitor the device's temperature and adjust the readings accordingly.
