TMPA2055DM 2.7-W MONO FILTER-FREE CLASS-D AUDIO POWER AMPLIFIER

The TMPA2055DM is a mono class-D filter–free audio power amplifier IC. 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. Two patents are pending. With common mode input structure, TMPA2055DM requires no input or output coupling capacitors. It also features high Common Mode Rejection Ratio and Po.

Features

high Common Mode Rejection Ratio and Power Supply Rejection Ratio. 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. 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（ Pulse Width Modulation） . ♦ Less Than 0.2uA Shutdown Current ♦ Popless Power-Up, Shutdown and Recovery ♦ Differential 230 KHz PWM Allows Bridge-Tied Load.
