The CXAR41261 were specifically designed to provide high quality output power with a minimal amount of external components. It requires no output coupling capacitors, for this reason, it is perfectly meet the needs of mobile phone and other low voltage applications where require the consumption of power in the smallest amount.The CXAR41261 can offer a low standby current and a zero shutdown current. Furthermore, the wake up time of the amplifier is fast enough to use shutdown mode as a mute function，The CXAR41261 has an advanced pop & click circuitry that eliminates the noise during turning on and turning off of the device.The is an audio power amplifier primarily designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 1 watts of continuous average power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5V DC power supply.
