The recommended layout and placement for the NAU8812RG can be found in the Nuvoton application note AN0331, which provides guidelines for PCB layout, component placement, and thermal management.
To optimize the NAU8812RG for low noise and high PSRR, ensure that the input and output capacitors are properly selected and placed, and that the PCB layout is designed to minimize noise coupling and electromagnetic interference (EMI). Additionally, consider using a low-noise voltage regulator and a high-PSRR capacitor at the output.
The NAU8812RG can handle a maximum input voltage of 18V, but it is recommended to operate within the specified input voltage range of 4.5V to 15V for optimal performance and reliability.
To ensure the NAU8812RG is stable and does not oscillate, follow the recommended component values and PCB layout guidelines, and ensure that the output capacitor is properly selected and placed. Additionally, consider adding a small ceramic capacitor (e.g., 10nF) in parallel with the output capacitor to improve stability.
The typical dropout voltage of the NAU8812RG is around 1.5V, but this can vary depending on the input voltage, output current, and temperature. Refer to the datasheet for more detailed information on dropout voltage characteristics.
