Description
The 4440 is a two channel audio power amplifier IC with dual channels built in, allowing it to be used in stereo and bridge amplifier applications. It produces 6 W per channel in dual mode and 19 W in bridge mode. It has a good ripple rejection of 46dB, low residual noise, overvoltage and surge voltage protection, and so on. The IC’s pin-to-pin protection is an excellent feature. 4440 Characteristics There are two built-in channels that can be used as Mono or Stereo. Dual operating modes 6W x 2 and 19W 46 dB Bridge mode Ripple rejection is 18V at maximum power handling and 12V on average. Low distortion and good channel separation Pin-to-Pin protection and audio muting are built in. Circuitry for surge protection
