2-W STEREO AUDIO POWER AMPLIFIER
WITH DirectPath STEREO HEADPHONE DRIVE AND REGULATOR
MicrosoftWindows Vista Compliant
The TPA6040A4 is a stereo audio power amplifier
and DirectPath headphone amplifier in a thermally
Fully Differential Architecture and High PSRR
enhanced, space-saving, 32-pin QFN package. The
Provide Excellent RF Rectification Immunity
speaker amplifier is capable of driving 2 W per
2-W, 10% THD+N Into 4- Speakers and
channel continuously into 4-
loads at 5 V. The
85-mW, 1% THD+N Into 16-
Headphones
headphone amplifier achieves a minimum of 85 mW
From 5-V Supply
at 1% THD+N from a 5-V supply. A built-in internal
DirectPath Headphone Amplifier Eliminates
4-step gain control for the speaker amplifier and a
fixed –1.5 V/V gain for the headphone amplifier
Output Capacitors (1)
minimizes external components needed.
Internal 4-Step Speaker Gain Control: 6, 10,
15.6, 21.6 dB and Fixed –1.5-V/V Headphone
Independent shutdown control and dedicated inputs
for
the
speaker
and
headphone
allow
the
4.75-V Low Dropout Regulator for CODEC
TPA6040A4
to
simultaneously
drive
both
Independent Shutdown Controls for Speaker,
headphones and internal speakers. Differential inputs
Headphone Amplifier, and Low Dropout
to the speaker amplifiers offer superior power-supply
Regulator (LDO)
and common-mode noise rejection.
