The TPA6130A2 is a stereo DirectPath™ headphone amplifier with
I2C digital volume control. The TPA6130A2 has minimal quiescent current
consumption, with a typical IDD 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 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
