TPA102
SLOS213D – AUGUST 1998 – REVISED SEPTEMBER 2004
150-mW STEREO AUDIO POWER AMPLIFIER
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
The TPA102 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 8-
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 an 8-
load from 5 V is 0.1% at 1 kHz, and less than 2% across the audio band of 20 Hz to
20 kHz. For 32-
loads, the THD+N is reduced to less than 0.06% at 1 kHz, and is less than 1% across the
audio band of 20 Hz to 20 kHz. For 10-k
loads, the THD+N performance is 0.01% at 1 kHz, and less than
0.02% across the audio band of 20 Hz to 20 kHz.
