MAX98502 high efficiency, D-class audio amplifier

The MAX98502 is a high-efficiency, D-class audio amplifier, and a wide power supply voltage range of battery power supply voltages with a constant output power, a wide range of boost converters operating in 2MHz, requires only a small external inductor (2.2μH) and capacitance. The automatic level controlling the tracking function of the battery, reducing the output swing of the low supply voltage, preventing the battery voltage from crashing. The differential input of the amplifier and the internal full differential design of the internal. The MAX98502 also has three gain settings (about 6dB, 15.5 decibels and 20dB), is a logical input selection. The MAX98502 is in a small, 0.5mm pitch 16 solder ball WLP package (2.1 mm x2.1 mm). It is specified by the temperature range of the extension grade -40 ° C to +85 ° C. Key feature Enhanced D output Integrated automatic level control Output Power 2.2W enters 8Ω, 10% THD + N 1.7W enters 8Ω, 1% THD + N 4.1W to 4Ω, 10% THD + N 3.4W to 4Ω, 1% THD + N Wide power supply voltage of 2.5V to 5.5V Undervoltage lockover protection High total efficiency 87% High-step switching frequency (up to 2MHz) Activity emission limit low EMI, technology area Heilind won the title of "2017 Huaqiang Electronic Network Quality Supplier" Tas5634300W stereo PurePath (TM) HD digital input efficient power level TAS2557 5.7W D-class audio amplifier with H-class boost and speaker detection function Ruckus NetWorks appointed Deng Weidong for the general manager of China China Site Electronic Technology Forum - Power Technology Practice Seminar held in Wuhan
