TPA6130A2,pdf(138-mW DirectPat

The TPA6130A2 is a stereo DirectPath™ headphone amplifier with I²C digital volume control. The TPA6130A2 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 16 loads.

The TPA6130A2 is a high fidelity amplifier with an SNR of 98 dB. A PSRR greater than 100 dB enables direct-to-battery connections without compromising the listening experience. The output noise of 9 µVrms (typical A-weighted) provides a minimal noise background during periods of silence.
