TPA112
SLOS212E – AUGUST 1998 – REVISED JUNE 2004
150-mW STEREO AUDIO POWER AMPLIFIER
150-mW Stereo Output
The TPA112 is a stereo audio power amplifier pack-
aged in an 8-pin PowerPAD MSOP package
Wide Range of Supply Voltages
capable of delivering 150 mW of continuous RMS
– Fully Specified for 3.3-V and 5-V Operation
power per channel into 8-
loads. Amplifier gain is
– Operational From 2.5 V to 5.5 V
externally configured by means of two resistors per
Thermal and Short-Circuit Protection
input channel and does not require external compen-
sation for settings of 1 to 10.
Surface-Mount Packaging
THD+N when driving an 8-
load from 5 V is 0.1% at
– PowerPAD MSOP
1 kHz, and less than 2% across the audio band of 20
– SOIC
Hz to 20 kHz. For 32-
loads, the THD+N is reduced
Standard Operational Amplifier Pinout
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.
