Product Brief CP2297 V1.0 Audio Power Amplifier Series 3.1W,Mono,Fully Differential Audio Power Amplifier with Internal Feedback Resistors .. General Description The CP2297 is a fully differential audio power amplifier designed for demanding audio applications. It is capable of delivering 3.1 watt of continuous average power to a 3Ω BTL load with less than 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.2V to 5.5V. Features like -86d B PSRR at 217Hz, improved RF-rectification immunity, the space-saving CSP9, DFN8, MSOP8 and SOP8-PP(EXP PAD)packages, the advanced pop & click circuitry, a minimal count of external ponents and low-power shutdown mode make the CP2297 ideal for wireless handsets. The CP2297 is unity-gain stable, and the gain can be configured by external input resistors and internal feedback resistors.
