TMPA205DS

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.

(1) Stresses beyond those listed under"absolute maximum ratings" may cause permanent damage to the device. These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under "recommended operating conditions "is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

The TMPA205DS is a stereo class-D filterfree audio power amplifier IC. It delivers up to 2.45W/Ch power into a 4 ohm load or 1.5W/Ch power into an 8 ohm load. Two patents are pending.

With common mode input structure, TMPA205DS requires no input or output coupling capacitors. It also 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).
