CP2261

Product Brief CP2261 V1.0 Audio Power Amplifier Series 2.8W/CH,Stereo,Fully Differential Audio Power Amplifier with Internal Feedback Resistors www.datasheet4u.com General Description The CP2261 is a stereo fully differential audio power amplifier designed for demanding audio applications. It is capable of delivering 2.8 watt of continuous average power to a 3Ω load with less than 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.2V to 5.5V. Features like -85dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving QFN16 package, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2261 ideal for wireless handsets and notebook computers. The CP2261 is unity-gain stable, and the gain can be configured by external input resistors and internal feedback resistors.
