TPA6110A2 www.ti.com SLOS314B – DECEMBER 2000 – REVISED MARCH 2011 150-mW STEREO AUDIO POWER AMPLIFIER Check for Samples: TPA6110A2 FEATURES 1 2 150 mW Stereo Output PC Power Supply Compatible – Fully Specified for 3.3 V and 5 V Operation – Operation to 2.5 V Pop Reduction Circuitry Internal Mid-Rail Generation Thermal and Short-Circuit Protection Surface-Mount Packaging – PowerPAD™ MSOP Pin Compatible With LM4881 DGN PACKAGE (TOP VIEW) BYPASS 1 8 IN1– GND 2 7 VO1 SHUTDOWN 3 6 VDD IN2– 4 5 VO2 DESCRIPTION The TPA6110A2 is a stereo audio power amplifier packaged in an 8-pin PowerPAD™ MSOP package capable of delivering 150 mW of continuous RMS power per channel into 16-Ω loads. 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. THD+N when driving a 16-Ω load from 5 V is 0.03% at 1 kHz, and less than 1% across the audio band of 20 Hz to 20 kHz. For 32-Ω loads, the THD+N is reduced to less than 0.02% at 1 kHz, and is less than 1% across the audio band of 20 Hz to 20 kHz. For 10-kΩ loads, the THD+N performance is 0.005% at 1 kHz, and less than 0.5% across the audio band of 20 Hz to 20 kHz.
