Overview
DATA SHEET HIGH-FIDELITY HEADPHONE AMPLIFIER TSDP1xx DESCRIPTION The TSDP1xx is a Cap less Direct Connect™ Ground-Referenced Output Headphone amplifier with independent left/right volume and GPIO control.
It provides high quality audio fidelity with SNR of 105dB and output power of 180mW per channel.
The differential inputs allow for flexible input configuration that maximizes noise rejection for best in class CMRR.
