4.1 Transient Response Simulation

The audio Codec TAC5112-Q1 is modeled in TINA-TI™ as the input of the audio amplifier, with an input waveform of a 10kHz sine wave at 1.789Vrms (2.53V peak). The simulation results show that the differential amplifier can output the desired voltage at the output terminal, with Vout= 2.53V = 1.789VRMS.
