The TPA0222 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-
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-
speakers, the TPA0222 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. 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
TPA0222 automatically switches into SE mode when the SE/BTL input is activated, and reduces the gain to
1 V/V.
The TPA0222 consumes only 18 mA of supply current during normal operation. A miserly shutdown mode
reduces the supply current to 150 A.
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 TPA0222 to operate at full power into 8-
loads at an ambient temperature of 85°C.
