TPA2010D1 www.ti.com SLOS417C – OCTOBER 2003 – REVISED SEPTEMBER 2007 APPLICATION INFORMATION FULLY DIFFERENTIAL AMPLIFIER The TPA2010D1 is a fully differential amplifier with differential inputs and outputs. The fully differential amplifier consists of a differential amplifier and a common-mode amplifier. The differential amplifier ensures that the amplifier outputs a differential voltage on the output that is equal to the differential input times the gain.

TPA2010D1 www.ti.com SLOS417C – OCTOBER 2003 – REVISED SEPTEMBER 2007 Decoupling Capacitor (CS) The TPA2010D1 is a high-performance class-D audio amplifier that requires adequate power supply decoupling to ensure the efficiency is high and total harmonic distortion (THD) is low. For higher frequency transients, spikes, or digital hash on the line, a good low equivalent-series-resistance (ESR) ceramic capacitor, typically 1 μF, placed as close as possible to the device VDD lead works best.

TPA2010D1 www.ti.com SLOS417C – OCTOBER 2003 – REVISED SEPTEMBER 2007 Effect on Audio The class-D amplifier outputs a pulse-width modulated (PWM) square wave, which is the sum of the switching waveform and the amplified input audio signal. The human ear acts as a band-pass filter such that only the frequencies between approximately 20 Hz and 20 kHz are passed. The switching frequency components are much greater than 20 kHz, so the only signal heard is the amplified input audio signal.
