description
The TPA0202 is a stereo audio power amplifier in a 24-pin TSSOP thermal package capable of delivering
greater than 2 W of continuous RMS power per channel into 3-
loads. The TPA0202 simplifies design and frees
up board space for other features. Full power distortion levels of less than 0.1% THD+N from a 5-V supply are
typical. Low-voltage applications are also well served by the TPA0202 providing 800-mW per channel into 3-
loads with a 3.3-V supply voltage.
The TPA0202 has integrated depop circuitry that virtually eliminates transients that cause noise in the speakers
during power up and when using the mute and shutdown modes.
Amplifier gain is externally configured by means of two resistors per input channel and does not require external
compensation for settings of 2 to 20 in BTL mode (1 to 10 in SE mode). 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 (often headphone drive) outputs are required to be SE, the TPA0202 automatically switches into SE mode
when the SE/BTL input is activated. Using the TPA0202 to drive line outputs up to 700 mW/channel into external
3-
loads is ideal for small non-powered external speakers in portable multimedia systems. The TPA0202 also
features a shutdown function for power sensitive applications, holding the supply current at 5
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 readily realized in multilayer PCB
applications. This allows the TPA0202 to operate at full power into 3-
loads at ambient temperature of up to
85
°C with 300 CFM of forced-air cooling. Into 8- loads, the operating ambient temperature increases to 100°C.
