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.
