Product Brief
CP2212 V1.0
Audio Power Amplifier Series
3W/CH, Stereo, Filterless, Class-D Audio Power Amplifier
www.datasheet4Gu.econmeral 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.
