TPA6130A2RTJR

Product Summary

The TPA6130A2RTJR is a stereo DirectPath headphone amplifier with I2C digital volume control. The TPA6130A2RTJR has minimal quiescent current consumption, with a typical I DD of 4 mA, making it optimal for portable applications. The I2C control allows maximum flexibility with a 64 step audio taper volume control, channel independent enables and mutes, and the ability to configure the outputs into stereo, dual mono, or a single receiver speaker BTL amplifier that drives 300 mW of power into 16Ω loads. The applicaitons of the TPA6130A2RTJR include Mobile Phones, Portable Media Players, Notebook Computers, High Fidelity Applications.
