MAX13301 4-Channel, Automotive Class D Audio Amplifier The MAX13301 combines four high-efficiency Class D amplifiers with integrated diagnostic hardware for reliable automotive audio systems, and delivers up to 80W at 10% THD+N per channel into 4I when operating from a 24V supply. The internal diagnostics evaluate each channel’s output impedance to check for shorts across the outputs, to the battery, or to ground. The I2C interface allows the system to query critical device parameters such as device temperature and output clipping. The device is programmable to four different I2C addresses. The audio amplifiers feature single-ended analog inputs with a common negative input. The MAX13301 has a fixed gain of 26dB. The Class D amplifier has 10 programmable switching frequencies between 300kHz and 750kHz. The BTL outputs are protected against short circuits and thermal overload. The outputs can be configured as a 2-, 3-, or 4-channel amplifier. The device provides 50V load-dump protection, and is offered in the thermally enhanced, 48-pin TSSOP-EPR package operating over the -40NC to +125NC temperature range.
