Product Summary

The TPA0112PWPR is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2 W of continuous RMS power per channel into 3-W loads. The TPA0112PWPR minimizes the number of external components needed, simplifying the design, and freeing up board space for other features. When driving 1 W into 8-W speakers, the TPA0112PWPR has less than 0.8% THD+N across its specified frequency range. Included within this device is integrated depop circuitry that virtually eliminates transients that cause noise in the speakers.
