Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep the analog and digital signals separate. Additionally, use short traces and avoid crossing digital and analog signals. Refer to the TI application note 'AN-1187 Four-Layer PCB Layout and Routing for the TLV1544' for more details.
Use a low-impedance signal source, such as a buffer amplifier, to drive the analog input pins. Additionally, use a shielded cable and connect the shield to the AGND pin to prevent noise pickup. You can also use a ferrite bead or a series resistor to filter out high-frequency noise.
The maximum sampling rate of the TLV1544ID is 200 kHz. However, the power consumption increases with the sampling rate. At 200 kHz, the power consumption is approximately 15 mW, while at 10 kHz, it is around 5 mW. You can adjust the sampling rate to balance power consumption and performance requirements.
The TLV1544ID has an internal calibration circuit that can be enabled by setting the CAL pin high. The calibration procedure involves shorting the analog input pins to the internal reference voltage, and then reading the output code. You can use the calibration data to correct for offset and gain errors. Refer to the TI application note 'AN-1242 Calibration and Testing of the TLV1544' for more details.
The TLV1544ID has a maximum operating temperature range of -40°C to 125°C. Temperature affects the device's performance, particularly the offset voltage and gain error. Ensure good thermal dissipation by using a heat sink or a thermally conductive PCB material. You can also use thermal compensation techniques, such as using a thermistor or a temperature sensor, to correct for temperature-related errors.
