DESCRIPTION  
The TPA0312 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 TPA0312 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 6 dB, 10 dB, 15.6 dB, and 21.6 dB (inverting) are provided, whereas SE gain is always configured as  
4.1 dB 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 TPA0312 automatically switches into SE mode when the SE/BTL  
input is activated, and this reduces the gain to 4.1 dB.  
The TPA0312 consumes only 6 mA of supply current during normal operation. A miserly shutdown mode  
reduces the supply current to 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 readily realized in multilayer PCB  
applications. This allows the TPA0312 to operate at full power into 8-Ω loads at an ambient temperature of 85°C.
