1.75-W 3-CHANNEL STEREO AUDIO POWER AMPLIFIER

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-Ω loads. The center channel output is a bridged tied load (BTL) configuration for delivering maximum output power from PC power supplies. Combining the SE Line Drivers and high power center channel Amplifiers in a single TSSOP package simplifies design and frees up board space for other features. Full power distortion levels of less than 0.25% THD+N into 4-Ω loads from a 5-V supply voltage are typical. Low-voltage application are also well served by the TPA0103 providing 800 mW to the center channel into 4-Ω loads with a 3.3-V supply voltage. By Texas Instruments
