1.25W Mono Audio Power Amplifier CXAB4110B is a mono Class-AB audio power amplifier designed for demanding applications in mobile phones and other portable media devices

   产品概述 返回TOPco1嘉泰姆

The CXAB4110B is a mono Class-AB audio power amplifier designed for demanding applications in mobile phones and other portable media devices. It is capable of delivering 1.25W of continuous output power to an 8Ω BTL load with less than 1% distortion (THD+N) from a 5VDC power supply. 

The CXAB4110B is specifically designed to provide high quality output power with a minimal number of external components. The CXAB4110B does not require output coupling capacitors or bootstrap capacitors, and is therefore ideal for use in mobile phones and other low voltage applications where minimal power consumption is a primary requirement. 

The CXAB4110B features a low-power shutdown mode. In the shutdown mode where a logic low is applied onto the SD pin, the amplifier is completely turned off and no supply current will flow through the device. 

The CXAB4110B also features advanced pop & click circuitry which eliminates noise which would otherwise occur during turn-on and turn-off transitions. The CXAB4110B is unity-gain stable and can be configured by external gain-setting resistors.
