| The CP2291 is an audio power amplifier designed for demanding audio applications. It is capable of delivering 3 watt of continuous average power to a 3¦¸ BTL load with less than 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.2V to 5.5V.Features like excellent RF-rectification immunity, the space-saving CSP9, DFN8 and MSOP8 packages, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2291 ideal for wireless handsets.The CP2291 is unity-gain stable, and the gain can be configured by external resistors. |
