2-W STEREO AUDIO POWER AMPLIFIER

WITH DirectPath™ STEREO HEADPHONE DRIVE AND REGULATOR

FEATURES

DESCRIPTION

•

Microsoft™ Windows Vista™ Compliant

•

Fully Differential Architecture and High PSRR

Provide Excellent RF Rectification Immunity

The TPA6045A4C is a stereo audio power amplifier

and DirectPath™ headphone amplifier in a thermally

enhanced, space-saving, 32-pin QFN package. The

speaker amplifier is capable of driving 2.1 W per

channel continuously into 4-Ω loads at 5 V. The

headphone amplifier achieves a minimum of 85 mW

at 1% THD+N from a 5-V supply. A built-in internal

4-step gain control for the speaker amplifier and a

fixed –1.5 V/V gain for the headphone amplifier

minimizes external components needed.

•
