MAX98360 Evaluation Systems Evaluates: MAX98360A/MAX98360B/ MAX98360C/MAX98360D (WLP) General Description Features The MAX98360 Evaluation Systems (EV Systems) are 2.5V to 5.5V Single-Supply Operation fully assembled and tested systems that evaluate the I2S, Left-Justified, or TDM Input MAX98360A/B/C/D mono Class D audio amplifiers. Five Selectable Gains (-3dB, 3dB, 6dB, 9dB, and The EV Systems consist of a MAX98360 Development 12dB) Board (DEV Board), Maxims Audio Interface Board III Audio Channel Select (Left, Right, and Mono Mix) (AUDINT3), and a USB cable. Filterless Operation It is recommended that the DEV Board be evaluated with the AUDINT3 board, as an EV System. MAX98360A Low EMI 2 and MAX98360C support the standard I S interface, and Complete Hardware System with Easy Setup, No MAX98360B and MAX98360D support standard left- Tools or Special Software Required justified mode. All MAX98360 variants support an 8-channel TDM digital audio interface. EV System Contents The AUDINT3 board provides the USB-to-PCM interface MAX98360 Development Board in addition to the 1.8V V supply needed to evaluate DDIO Audio Interface Board III the DEV Board. The MAX98360 DEV Board requires one additional supply input, 2.5V5.5V (V ) when evaluating Micro-USB Cable DD using the AUDINT3 board. Figure 1 details the DEV Board and the AUDINT3 board.
