Q: Are there plans to have any MAX98390 support integrated with Audio Weaver (https://w.dspconcepts.com/audio-weaver) or any other additional software beyond the DSM Sound Studio?
A: Currently (7/31…
MAX98390 only supports 1.8V I2S. For QCOM plafforms, customers can connect MAX98390's I2S port to QCOM AP's 1.8V I2S ports. For Intel plaftorms, customers can connect MAX98390's I2S port to Realtek codec…
No calibration is required on the I/V sense ADC. The I/V sense uses an internally generated reference, and each device is trimmed for accuracy in production test, providing a typical accuracy of ~2% for…
The I and V data is formatted in 16-bit 2s complement format, with Voltage Sense Range = +/-11V, and Current Sense Range = +/-3A.
For Voltage Sense, if MSB is 0 then the voltage would be 11/(2^15) x…
First make sure that the speaker device provided with the valuation kit is being used for this debug, and the initial "Play Test Track" part of the GUI is working properly before proceeding. If "Play Test…
Question:
We are currently evaluating MAX98390 for a real-time wearable voice self-amplification application. We are considering the use of a supercapacitor to smooth peak power and decrease the maximum…
The voltage and current sensing on MAX98390 (I/V Sense) was designed to be used by the on-board DSP for the Dynamic Speaker Management speaker protection algorithm. The I/V sense data can be configured…

If CLASS D amplifier outputs are not properly filtered, it will result in PWM making its way to the analyzer which could be confused with high distortion audio. It is important to see that the signal making…
