TA2020-020
Overview
The TA2020-020 is a 20W continuous average two-channel Class-T Digital Audio Power TM 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.
- saturated square wave output Benefits ¾Fully integrated solution with FETs ¾ Easier to design-in than Class-D ¾ Reduced system cost with no heat sink ¾Dramatically improves efficiency versus Class-AB ¾Signal fidelity equal to high quality linear amplifiers ¾High dynamic range compatible with digital media such as CD, DVD, and internet audio ¾High Efficiency ¾88% @ 12W 8Ω ¾81% @ 20W 4Ω ¾Dynamic Range = 103 dB ¾Up to 2X25Wrms @ 4Ω, VDD=14.6V ¾Mute and Sleep inputs ¾Turn-on & turn-off pop suppression ¾Over-current protection ¾Over-temperature protection ¾Bridged outputs ¾32-pin SSIP package Typical Performance THD+N versus Output Power
