产品概述 返回TOP
The CXAR41200 is a stereo audio power amplifier that is designed for demanding applications in mobile phones and other portable communication device applications. It is capable of delivering 2.6W of continuous average power per channel into a 4Ω load with typically 10% distortion (THD+N) from a 5V power supply.
The CXAR41200 features an externally controlled, low power consumption shutdown mode and thermal shutdown protection. It also utilizes circuitry to reduce “pop/click” during device turn-on.
The CXAR41200 is unity-gain stable and can be configured by external gain-setting resistors.
The CXAR41200 is available in Green TQFN-4×4-16L package. It operates over an ambient temperature range of -40℃ to +85℃.
