Stereo 300W (4) Class-T Digital Audio Amplifier Driver using Digital Power ProcessingTM Technology TA3020
PRELIMINARY – January 2001
General Description
The TA3020 is a two-channel, 300W (4) per channel Amplifier Driver IC that uses Tripath’s TM proprietary Digital Power Processing (DPP ) technology. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.
Applications
!"Audio/Video Amplifiers & Receivers !"Pro-audio Amplifiers !"Automobile Power Amplifiers !"Subwoofer Amplifiers
Features
!"Class-T architecture !"Proprietary Digital Power Processing technology !"“Audiophile” Sound Quality !"0.02% THD+N @ 50W, 8 !"0.03% IHF-IM @ 30W, 8 !"High Efficiency !"95% @ 150W @ 8 !"90% @ 275W @ 4 !"Supports wide range of output power levels !"Up to 300W/channel (4), single-ended outputs !"Up to 1000W (4), bridged outputs !"Output over-current protection !"Over- and under-voltage protection !"48-pin DIP (dual-inline package)
Benefits
!"Reduced system cost with smaller/less expensive power supply and heat sink !"Signal fidelity equal to high quality Class-AB amplifiers !"High dynamic range compatible with digital media such as CD and DVD
