MAX13301 - 4通道、汽车应用D类音频放大器 - 音频芯片 - 支持较宽的工作电压(6V至25.5V)范围，提供汽车诊断和抛负载保护 - 美信半导体
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 4Ω 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 -40°C to +125°C temperature range.
