An apparatus for generating an analog signal and methods of operating the same results in a cost effective solution for an audio sound generator. The apparatus for generating an analog signal comprises an I.sup.2 C interface configured to provide programming data in response to write control signals, a non-volatile memory coupled to the I.sup.2 C interface configured to store the programming data, a pulse width modulator coupled to the non-volatile memory configured to receive the programming data from the non-volatile memory and provide a pulse width modulated output in response to the programming data, and a d/a converter coupled to the non-volatile memory configured to receive the programming data from the non-volatile memory and provide an analog output in response to the programming data. The pulse width modulated output can be coupled to a piezoelectric speaker to produce audible sound. The analog output provides a line out signal that can be coupled to a dynamic speaker.
