TPA0103 - Texas Instruments

TPA0103 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 .

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. 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 fro.
