Product Overview

The TPA6130A2RTJR is a 138mW DirectPath™ Stereo Headphone Amplifier with I²C digital volume control. The TPA6130A2 has minimal quiescent current consumption, with a typical IDD of 4mA 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 300mW of power into 16Ω loads. This is a high fidelity amplifier with an SNR of 98dB. A PSRR greater than 100dB enables direct-to-battery connections without compromising the listening experience. The output noise of 9µVrms (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.
  • DirectPath™ ground-referenced outputs
  • Eliminates output DC blocking capacitors
  • Full bass response without attenuation
  • 64 Step audio taper volume control
  • High power supply rejection ratio (>100dB PSRR)
  • Differential inputs for maximum noise rejection (68dB CMRR)
  • High impedance outputs when disabled
  • Advanced pop and click suppression circuitry
  • Digital I²C bus control
  • Green product and no Sb/Br
