Product Details

describe:

The TPA6133A2 is a stereo DirectPath™ headphone amplifier with GPIO control. The TPA6133A2 has minimal quiescent current consumption with a typical I DD of 4.2 mA, making it the best choice for portable applications. GPIO control allows placing the device in a low-power shutdown mode.

The TPA6133A2 is a high-fidelity AOP607 amplifier with an SNR of 93 dB. A PSRR greater than 100 dB enables direct connection to the battery without compromising the listening experience. 12 μVrms (typically A-weighted) output noise provides minimal noise background during quiet periods. Configurable differential inputs and high CMRR allow for maximum noise rejection in the noisy environment of mobile devices.
