FEATURES  
DESCRIPTION  
The TPA6133A2 is a stereo DirectPath™ headphone  
amplifier with GPIO control. The TPA6133A2 has  
minimal quiescent current consumption, with a typical  
IDD of 4.2 mA, making it optimal for portable  
applications. The GPIO control allows the device to  
be put in a low power shutdown mode.

Full Bass Response Without Attenuation  
The TPA6133A2 is a high fidelity amplifier with an  
SNR of 93 dB. A PSRR greater than 100 dB enables  
direct-to-battery connections without compromising  
the listening experience. The output noise of 12  
μVrms (typical A-weighted) provides a minimal noise  
background during periods of silence. Configurable  
differential inputs and high CMRR allow for maximum  
noise rejection in the noisy environment of a mobile  
device.
