一.产品概述
The CXAU4131 is a bridge-connected audio power amplifier capable of delivering typically 1.7W of continuous average power to an 6Ω load from a 5V power supply and up to 2W if DIP8 package. Boomer audio power amplifiers were designed specifically to provide high quality output power with a minimal amount of external components. Since the CXAU4131 does not require output coupling capacitors, bootstrap capacitors, or snuber networks, it is optimally suited for low-power portable systems. The CXAU4131 features an externally controlled, low-power consumption shutdown mode, as well as an internal thermal shutdown protection mechanism. The unity-gain stable CXAU4131 can be configured by external gain-setting resistors.
