description
The TPA0212 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-
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 TPA0212 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.
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 TPA0212 automatically switches into SE mode when the SE/BTL input is activated, and
this reduces the gain to 1 V/V.
The TPA0212 consumes only 6 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 readily realized in multilayer PCB
applications. This allows the TPA0212 to operate at full power into 8-
Ω loads at an ambient temperature of 85°C.
