Beschreibung

• MAX98358EVSYS#TQFN, Evaluation System (DEV + AUDINT) for the MAX98358 PDM Input Class-D Audio Power Amplifier. The MAX98358 evaluation system (EV SYS) operates from a single 2.5V to 5.5V DC power supply and is capable of delivering 3.2W into a 4-ohm load. The device outputs can be connected directly to a speaker load for filterless applications. However, a filter can be added to ease evaluation. The EV SYS includes the DEV board, PDM Generator board (PDM GEN) and the Maxim Audio Interface board (AUDINT board). The AUDINT board provides an easy-touse USB audio to I2S converter. The I2S data is fed into the PDM generator board that uses an FPGA to convert the I2S data stream into a PDM data stream. This allows for any computer to become a digital audio source that can be used to evaluate the device
