The TPA0103 is a 3-channel audio power amplifier in a 24-pin TSSOP thermal package primarily targeted at desktop PC or notebook applications. The left/right (L/R) channel outputs are single ended (SE) and capable of delivering 500 mW of continuous RMS power per channel into 4-loads with a 3.3-V supply voltage.
Amplifier gain is externally configured by means of two resistors per input channel and does not require external compensation for settings of 1 to 10. A two channel input MUX circuit is integrated on the L/R channel inputs to allow two sets of stereo inputs to the amplifier. In the typical application, the center channel amplifier is driven from a mix of the L/R inputs to produce a monaural representation of the stereo signal. The center channel amplifier can be shut down independently of the L/R output for speaker muting in headphone applications. The TPA0103 also features a full shutdown function for power sensitive applications holding the bias current to 5 uA.
The PowerPAD package (PWP) delivers a level of thermal performance that was previously achievable only in TO-220-type packages. Thermal impedances of less than 35°C/W are readily realized in multilayer PCB applications. This allows the TPA0103 to operate at full power at ambient temperature of up to 85°C.
