LM4871MM Frequently Asked Questions (FAQs)
-
Texas Instruments provides a recommended PCB layout in the datasheet, but it's also important to follow general high-frequency layout guidelines, such as keeping the input and output traces short and away from each other, and using a solid ground plane to reduce noise and EMI.
-
The choice of input and output capacitors depends on the specific application and frequency range. In general, X7R or X5R ceramic capacitors with a voltage rating of at least 2x the maximum input voltage are recommended. The output capacitor should be chosen based on the desired output impedance and ripple voltage.
-
The maximum power dissipation of the LM4871MM is dependent on the ambient temperature and the thermal resistance of the package. According to the datasheet, the maximum power dissipation is 1.4W at 25°C, but this can be derated to 0.7W at 85°C. It's essential to ensure proper thermal design and heat sinking to prevent overheating.
-
Yes, the LM4871MM can be used in a stereo audio application. The device has a differential input stage, which allows it to reject common-mode noise and provide a high common-mode rejection ratio (CMRR). This makes it suitable for stereo audio applications where a high-quality audio signal is required.
-
To filter out noise and EMI, it's essential to use proper filtering techniques, such as adding ferrite beads or chokes to the input and output lines, and using shielding and grounding techniques to reduce radiated emissions. Additionally, the LM4871MM has a built-in EMI filter, which can be enabled by connecting the EMIF pin to VCC or GND.
