CP2212

Product Brief CP2212 V1.0 Audio Power Amplifier Series 3W/CH, Stereo, Filterless, Class-D Audio Power Amplifier General www.datasheet4u.com Description The CP2212 is a high efficiency, stereo, filterless, Class D audio power amplifier designed for demanding audio applications. It is capable of delivering 3W/CH of continuous average power to a 4Ω BTL load with less than 10% distortion (THD+N) from a 5V battery voltage. It operates from 2.5V to 5.5V. Features like 90% efficiency, -80dB PSRR at 217Hz, improved RF-rectification immunity, the space-saving CSP16 and QFN20 packages, the advanced pop & click circuitry, a minimal count of external components and low-power shutdown mode make the CP2212 ideal for wireless handsets. The CP2212 features independent shutdown controls for each channel. The gain can be selected to 6, 12, 18, or 24 dB utilizing the G0 and G1 gain select pins.
