Description

IU86751E is a 2x28W stereo; in the case of monophonic use; it can output up to 50W of high-efficiency Class D audio power amplifier circuit. Advanced EMI suppression technology allows the use of cheap ferrite bead filters at the output port to meet EMC requirements. IU86751E audio power amplifier is designed for systems that need to output high-quality audio power. It uses surface mount technology and only requires a small number of peripheral devices to enable the system to have high-quality audio output power. IU86751E has built-in over-current protection, short-circuit protection and over-temperature protection, which effectively protects the chip from being damaged under abnormal working conditions. IU86751E can drive speakers with loads as low as 4Q and can provide up to 50W of continuous power; IU86751E has an efficiency of up to 92%, so no additional heat sink is required when playing music. Large power supply voltage range 5V~20V, efficiency up to 92%, no heat sink required, fixed 40x gain, integrated 10K input resistor, 400K feedback resistor, spread spectrum function, differential input. The audio system has a filter network, standby current is less than 20mA, no filtering function is required, output pins are convenient for wiring layout, good short-circuit protection and temperature protection with automatic recovery function, good distortion and anti-pop function. IU86751E is available in a compact E QA16 package, which is the same size as ESOP8 and can save customers considerable PCB area. Its rated operating temperature range is -40°C to 85°C.
