Classification: CPC H | IPC H

Claim 13:
14. An apparatus, comprising:
an audio amplifier configured to amplify an input audio signal to generate an output audio signal for driving a load, comprising:
a package terminal array comprising a plurality of terminals, wherein a spacing between the plurality of terminals is less than 0.5 mm;
a differential amplifier comprising a first high-voltage circuit configured to amplify a first signal of a differential signal to produce a first high-voltage output signal at a first terminal of the package terminal array, the differential amplifier further comprising a second high-voltage circuit configured to amplify a second signal of the differential signal to produce a second high-voltage output signal at a second terminal of the package terminal array,
wherein the first high-voltage circuit and the second high-voltage circuit are positioned symmetrically around an axis through the audio amplifier, and
wherein the first terminal and the second terminal are located at an edge of the package terminal array;
a control circuit comprising gate drivers configured to control the first high-voltage circuit and the second high-voltage circuit of the differential amplifier,
wherein the control circuit is positioned between the first high-voltage circuit and the second high-voltage circuit.
