2.7-W MONO CLASS-D AUDIO POWER AMPLIFIER
GENERAL DESCRIPTION
The TMPA2155DM is a mono class-D audio power amplifier IC.
With BTL(Bridge-Tied-Load) configuration, it delivers up to
2.7W power into a 3 ohms load or 2.3W power into a 4 ohm load
or 1.5W power 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.
