TPA6111A2
SLOS313B – DECEMBER 2000 – REVISED JUNE 2004
150-mW STEREO AUDIO POWER AMPLIFIER
• 150-mW Stereo Output
The TPA6111A2 is a stereo audio power amplifier
packaged in either an 8-pin SOIC or an 8-pin
• PC Power Supply Compatible
PowerPAD™ MSOP package capable of delivering
– Fully Specified for 3.3-V and
150 mW of continuous RMS power per channel into
5-V Operation
16-Ω loads. Amplifier gain is externally configured by
– Operation to 2.5 V
means of two resistors per input channel and does
not require external compensation for settings of 0 to
• Pop Reduction Circuitry
20 dB.
• Internal Midrail Generation
THD+N, when driving a 16-Ω load from 5 V, is 0.03%
• Thermal and Short-Circuit Protection
at 1 kHz, and less than 1% across the audio band of
• Surface-Mount Packaging
20 Hz to 20 kHz. For 32-Ω loads, the THD+N is
– PowerPAD™ MSOP
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
– SOIC
10-kΩ loads, the THD+N performance is 0.005% at 1
