The CXAR41201 is a mono bridged audio power amplifier that is designed for portable communication device applications and demanding applicationsin mobile phones. CXAR41201YPS8 is capable of delivering 2.4W of continuous average power into a 4Ω load with typically 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.5V to 5.5V power supply.
The CXAR41201’smicro-power shutdown mode (ISD = 0.07μA TYP) is activated when V+ is applied to the SHDN pin. Since the CXAR41201 does not require output coupling capacitors, bootstrap capacitors, or snubber networks, it is ideally suited for low power portable systems that require minimum volume and weight.
The CXAR41201 is unity-gain stable and can be configured by external gain-setting resistors. Additionally, the CXAR41201 features an internal thermal shutdown protection mechanism.
The CXAR41201 is available in Green SOIC-8 and SOIC-8 (Exposed Pad) packages. It operates over an ambient temperature range of -40℃ to +85℃.
