Texas Instruments recommends a 4-layer PCB with a solid ground plane, and to keep analog and digital signals separate. Use short, direct traces for analog signals and avoid crossing digital signals over analog signals. Also, use a common mode filter capacitor between the analog input and the analog ground.
To optimize the ADC3441IRTQT for low-power applications, use the lowest possible clock frequency, disable the internal reference voltage, and use the power-down mode when not converting. Additionally, consider using a lower supply voltage and reducing the input bandwidth.
The ADC3441IRTQT has an internal calibration feature that can be initiated by writing to the calibration register. The calibration process takes approximately 100 μs and should be performed after power-up or after a change in the operating conditions. It is recommended to perform calibration at the beginning of each conversion cycle.
The ADC3441IRTQT has an internal overvoltage protection circuit that can withstand up to 6 V on the analog input. However, it is recommended to use external protection circuitry, such as a voltage clamp or a resistive divider, to prevent damage from excessive voltage levels.
To synchronize multiple ADC3441IRTQT devices, use a common clock source and synchronize the conversion cycles by asserting the CONVST pin simultaneously on all devices. Additionally, ensure that the devices are configured to use the same clock frequency and conversion mode.
