| The CP2268 is a stereo fully differential audio power amplifier designed for demanding audio applications. It is capable of delivering 2.6 watt of continuous average power to a 3Ωload with less than 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.2V to 5.5V.Features like -86dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving QFN16 and CSP16 packages, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2268 ideal for wireless handsets and notebook computers.The CP2268 is unity-gain stable, and the gain can be configured by external resistors. |
