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 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.
