Abstract:
A signal amplifier includes a pulse width modulator, a level shifter, and a power amplifier. The pulse width modulator is driven by a positive power supply and a negative power supply, and a reference voltage of the pulse width modulator is set to a GND. The power amplifier is driven by a positive power supply, and a reference voltage of the power amplifier is set to a middle value between the positive power supply and the GND. The level shifter shifts a voltage level of a first PWM signal whose high level corresponds to the positive power supply of the pulse width modulator and whose low level corresponds to the negative power supply of the pulse width modulator, to a voltage level of a second PWM signal whose high level corresponds to the positive power supply of the power amplifier and whose low level corresponds to the GND.

Claim (Index 4):
The signal amplifier according to  claim 1 , wherein\n the analog input signal of a single-ended form is input to the signal input unit, and the analog output signal of a differential form is output from the signal output unit.
