    Application Circuit :




    The AP4890K is a 1.4 Watt audio power amplifier. And the AP4890K primarily designed for high Quality

    application in other portable communication device.It is capable of driving 8Ω speaker load at a continuous

    average output of 1.4W / 10% distortion (THD+N) from a 5.0V power supply. A feature of the AP4890K amplifier

    to switch BTL mode. And the AP4890K audio amplifier features low power consumption shutdown mode. It is

    achieved by driving the shutdown pin with logic high. Besides the AP4890K has an internal thermal shutdown

    protection feature.

    The AP4890K amplifier was designed specifically to provide high quality output power with a  minimal amount

    of external components. The AP4890K does not require output capacitors, and the AP4890K is ideally suited

    for other low voltage applications or portable electronic devices where minimal power consumption is a primary
