2.7W/CH STEREO CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The TMPA2155DS is a stereo class-D audio power amplifier
IC. With BTL(Bridge-Tied-Load) configuration, it delivers up
to 2.7W/ch(5.4W in all) into a 3 ohm load or 2.3W/ch(4.6W in
all) into a 4 ohm load or 1.5W/ch(3W in all) into an 8 ohm load.
No external heat-sink is required.
For multiple-input applications, independent gain control and
corner frequency can be implemented by summing the input
sources through resistor ratio and input capacitor values.
Automatic voltage gain control makes the best use of battery.
Analog input signal is converted into digital output which
drives directly to the speaker. High power efficiency is
achieved due to digital output at the load. The audio
information is embedded in PWM
（
APPLICATIONS
Pulse Width Modulation
）
.
Multimedia application includes Cellular Phones, PDAs,
DVD/CD players, TFT LCD TVs/Monitors, 2.1 channel/5.1
channel audio systems, USB audio. It is also ideal for other
portable devices like Wireless Radios.
