TPA0212PWPRG4

Product Summary

The TPA0212PWPRG4 is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2.6 W of continuous RMS power per channel into 3-W loads. The TPA0212PWPRG4 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 TPA0212PWPRG4 has less than 0.65% 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. Amplifier gain is internally configured and controlled by way of two terminals (GAIN0 and GAIN1). BTL gain settings of 2, 6, 12, and 24 V/V are provided, while SE gain is always configured as 1 V/V for headphone drive. An internal input MUX allows two sets of stereo inputs to the amplifier. The HP/LINE terminal allows the user to select which MUX input is active regardless of whether the amplifier is in SE or BTL mode. In notebook applications, where internal speakers are driven as BTL and the line outputs (often headphone drive) are required to be SE, the TPA0212PWPRG4 automatically switches into SE mode when the SE/BTL input is activated, and this reduces the gain to 1 V/V.
