CS8683 mono class D 130W audio power amplifier chip, low no-load current, AM suppression function

CS8683H is a 90W mono Class-D audio amplifier. This device has a heat sink designed on the top layer. After connecting a heat sink to the pad, it can achieve a power output of more than 100W and can drive a load as low as 20 under an appropriate power supply voltage. CS8683H has advanced EMI suppression technology. 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.

CS8683H has built-in over-current protection, short-circuit protection and over-heat protection, which effectively protect the chip from being damaged under abnormal working conditions. CS8683H can achieve a maximum efficiency of more than 92%, and the voltage resistance design of more than 45V provides ultra-high reliability for the chip, which can effectively reduce the defective ratio in the production process.

CS8683H provides a special EQB32 package for customers to choose. The appropriate package size provides the greatest convenience for customers to install heat dissipation devices. Its rated operating temperature range is -40℃ to 85℃.
