AX4001-3W Audio Power Amplifier Shutdown Mode

AX4001-3W Audio Power Amplifier with Shutdown Mode DataSheet

GENERAL DESCRIPTION
    The AX4001 is a mono bridged audio power amplifier capable of delivering 3W of continuous average power into a 3Ω load with less than 10% THD when powered by a 5V power supply. It does not require output coupling capacitors or bootstrap capacitors, and is ideal for mobile phone and other low voltage applications where minimal power consumption is a primary requirement.
    The AX4001 features a low-power consumption shutdown mode, and an internal thermal shutdown protection mechanism. Advanced pop & click circuitry is built in to eliminate noises that would otherwise occur during turn-on and turn-off transitions. The AX4001 is unity-gain stable and can be configured by external gain-setting resistors.
    AXElite products are RoHS and Halogen free compliant.
