A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the analog and digital grounds separate and connect them at a single point. Use a 10nF capacitor between the VCC and GND pins to filter out noise.
Ensure the power supply is stable and within the recommended voltage range (1.8V to 3.6V). Use a 10kΩ pull-up resistor on the EN pin to enable the device. Configure the device using the I2C interface, following the protocol outlined in the datasheet.
The maximum current draw of the MAX98400BETG+ is 1.5mA (typical) when operating at 1.8V. However, this can vary depending on the specific application and operating conditions.
Use a logic analyzer or oscilloscope to monitor the I2C bus and verify the device is receiving the correct commands. Check the power supply and ensure it is within the recommended range. Verify the PCB layout and ensure it meets the recommended guidelines.
The MAX98400BETG+ is rated for operation up to 85°C. However, the device's performance may degrade at higher temperatures. Ensure proper thermal management and consider using a heat sink if operating in high-temperature environments.
