The TPA0252 is a stereo audio power amplifier in a 24-pin TSSOP thermally enhanced package capable of delivering 2.8 W of continuous RMS power per channel into 3-
speakers, the TPA0252 has less than 0.3% THD+N across its specified frequency range. The integrated depop circuitry virtually eliminates transients that cause noise in the speakers.
Amplifier gain is controlled by two terminals, UP\ and DOWN\. There are 31 discrete steps covering the range of 20 dB (maximum volume setting) to –40 dB (minimum volume setting) in 2 dB steps. By pressing either button momentarily, the volume steps up or down 2 dB. By continuing to hold the button down, the device starts stepping through volume settings at a rate determined by the capacitor on the CLK terminal.
