138-mW DIRECTPATH™ STEREO HEADPHONE AMPLIFIER

Check for Samples: TPA6133A2

FEATURES

DESCRIPTION

The TPA6133A2 is a stereo DirectPath™ headphone

amplifier with GPIO control. The TPA6133A2 has

minimal quiescent current consumption, with a typical

I_DDof 4.2 mA, making it optimal for portable

applications. The GPIO control allows the device to

be put in a low power shutdown mode.

–

Eliminates Output DC Blocking Capacitors

Reduces Board Area

Reduces Component Height and Cost

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.
