General Description
The CP2215 is a high efficiency, mono, filterless, Class D audio power
amplifier with spread spectrum designed for demanding audio
applications. An advanced spread spectrum modulation reduces EMI
and eliminates output filter. It is capable of delivering 3W 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 CSP9 and DFN8 packages,
the advanced pop & click circuitry, a minimal count of external
components and low-power shutdown mode make the CP2215 ideal for
wireless handsets.
The gain of the CP2215 can be configured by external input resistors,
which allows independent gain control from multiple sources by
summing the signals. Short circuit and thermal protection prevent the
device from damage during fault conditions.
