无需滤波器D类音频功放.2.7W抗EMI干扰.短路保护 CS6105

GENERAL DESCRIPTION

The ft2011 is a high efficiency, low EMI, filterless,
Class-D audio amplifier with auto-recovering
short-circuit protection. It operates from 3V to
5.5V supply. When powered with 5V supply
voltage, the ft2011 is capable of delivering 3W
into a 4Ω load or 1.8W into an 8Ω load, with 10%
THD+N.

As a Class-D audio amplifier, the ft2011 features
90% efficiency and 75dB PSRR at 217Hz which
make the device ideal for battery-powered
high-quality audio applications.

One of the key benefits of the ft2011 over typical
Class-D audio power amplifiers is it generates
much less EMI emissions, thus greatly simplifying
the system design for portable applications. Also
included is the over-current and short-circuit
protection with auto-recovery, which ensures the
device be operated safely and reliably without the
need for system interaction.
