TECHNICAL INFORMATION
Stereo 10W (4Ω) Class-T™ Digital Audio Amplifier using
Digital Power Processing™ Technology
TA1101B
September 2000
General Description
The TA1101B is a 10W continuous average two-channel Class-T Digital Audio Power
Amplifier IC using Tripath’s proprietary Digital Power Processing™ technology. Class-T
amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D
amplifiers.
Applications
