Preliminary data sheet Rev. 01 — 9 September 2008 5 of 39 NXP Semiconductors TDA8950 2 × 150 W class-D power amplifier 7.2 Pin description 8. Functional description 8.1 General The TDA8950 is a two-channel audio power amplifier using class-D technology. The audio input signal is converted into a digital pulse width modulated signal via an analog input stage and PWM modulator, see Figure 1. To enable the output power transistors to be driven, this digital PWM signal is applied to a control and handshake block and driver circuits for both the high side and low side. In this way a level shift is performed from the low power digital PWM signal (at logic levels) to a high power PWM signal that switches between the main supply lines. A 2nd-order low-pass filter converts the PWM signal to an analog audio signal across the loudspeakers. Table 3.
