GENERAL DESCRIPTION
The LY8221 is a 3.0W stereo, high efficiency class
D audio power amplifier. It is a low noise, filterless,
PWM architecture eliminates the output filter,
reducing external component count, BOM (system)
cost, and simplify design.
The LY8221 features a low power consumption in
shutdown mode and thermal shutdown protection. It
also utilizes circuitry to reduce low noise during
device turn-on.
The outputs are also fully protected against short to
GND, VDD, and output-to-output. The short-circuit
protection and thermal protection include an
auto-recovery feature.
LY8221 support the 3D function. When selectable
the 3D enhance mode function provides enhanced
stereo imaging.
APPLICATION
„ Portable electronic devices.
„ Mobile Phones.
„ Multimedia TFT LCD TVs / Monitors.
