CP2293 V1.0
Audio Power Amplifier Series
3W,Mono, Fully Differential Audio Power Amplifier
General www.datasheet4u.com Description
CSP8 Package 1.5mm х 1.5mm -40℃~85℃
The CP2293 is a fully differential audio power amplifier designed for demanding audio applications. It is capable of delivering 3 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 -88dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving CSP8, DFN8 and MSOP8 packages, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2293 ideal for wireless handsets. The CP2293 is unity-gain stable, and the gain can be configured by external resistors.
