The recommended PCB layout for the MAX98090BETL+ involves placing the device near the audio codec, using a solid ground plane, and minimizing the length of the analog signal traces. A 4-layer PCB with a dedicated ground plane is recommended.
To optimize the performance of the MAX98090BETL+ in a noisy environment, use a low-ESR capacitor for the AVDD pin, add a 10uF capacitor between AVDD and AGND, and use a shielded cable for the audio signal. Additionally, consider using a common-mode choke or a ferrite bead to filter out high-frequency noise.
The maximum power consumption of the MAX98090BETL+ is approximately 120mW when operating at a supply voltage of 1.8V and a clock frequency of 24.576MHz.
The MAX98090BETL+ can be configured for a specific audio application by programming the device's registers using a serial interface such as I2C or SPI. The device's datasheet provides a detailed description of the register map and the available configuration options.
The thermal resistance of the MAX98090BETL+ is approximately 30°C/W (junction-to-ambient) when mounted on a 4-layer PCB with a dedicated ground plane.
