The CS5290E is a capacitive boost type GF mono audio amplifier using CMOS technology, which can provide up to 5.2W continuous power for 40 loads. CS5290E chip internal fixed 28 times gain, effectively reduce the number of peripheral components, the power amplifier integrated D and AB two working modes can ensure the strong power output in the class D mode, but also take into account the system in the case of FM, eliminate the power amplifier to the system interference;        The CS5290E features a unique NCN function that automatically adjusts the amplifier's gain according to the size of the output signal for a more comfortable hearing experience.
    The CS5290E is an ideal audio subsystem amplifier solution for mobile audio devices powered by lithium batteries, with only a low cost containment component on the periphery. CS5290E's fully differential architecture and extremely high PSRR effectively improve the CS5290E's ability to suppress RF noise. In addition, CS5290E has built-in overcurrent protection and overheat protection, which effectively protects the chip from being damaged under abnormal working conditions.
    The CS5290E offers the ESOP10 package type with a rated operating temperature range of -40 ° C to 85 ° C.
