Description
The TDA8950TH/N1 is a high efficiency, two channel class D audio power amplifier in 24 pin HSOP package. The typical output power is 2 x 150W with speaker load impedance of 4ohm. For each channel, the audio input signal is converted into a digital PWM signal using an analogue input stage and PWM modulator. The TDA8950TH/N1 contains high power switches, drivers, timing and handshaking between power switches along with some control logic. To ensure maximum system robustness, an advanced protection strategy has been implemented to provide overvoltage, overtemperature and overcurrent protection. Each of the two audio channels contains PWM modulator, analogue feedback loop and differential input stage.
