TPA6130A2RTJR

TEXAS INSTRUMENTS  TPA6130A2RTJR  音频功率放大器, AB, 2通道, 138 mW, 2.5V 至 5.5V, QFN, 20 引脚

The 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 16R 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.
