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

Ω 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. Configurable differential inputs and

high CMRR allow for maximum noise rejection in the noisy environment of a mobile device.

TPA6130A2 packaging includes a 2 by 2 mm chip-scale package, and a 4 by 4 mm QFN package.
