DESCRIPTION  
The TPA0122 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-Ω loads. This device minimizes the number of  
external components needed, simplifying the design, and freeing up board space for other features. When driving  
1 W into 8-Ω speakers, the TPA0122 has less than 0.5% 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 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. In notebook applications, where internal speakers are  
driven as BTL and the line outputs (often headphone drive) are required to be SE, the TPA0122 automatically  
switches into SE mode when the SE/BTL input is activated and reduces the gain to 1 V/V.  
The TPA0122 consumes only 18 mA of supply current during normal operation. A miserly shutdown mode  
reduces the supply current to less than 150 µA.  
The PowerPAD package (PWP) delivers a level of thermal performance that was previously achievable only in  
TO-220-type packages. Thermal impedances of approximately 35°C/W are truly realized in multilayer PCB  
applications. This allows the TPA0122 to operate at full power into 8-Ω loads at an ambient temperature of 85°C.
