General Description
The TA2021B is a 25W (4Ω) continuous average per channel Class-T Digital Audio Power Amplifier IC using Tripath’s proprietary Digital Power Processing (DPPTM) technology. Class-T amplifiers offer both the audio fidelity of Class-AB and the power efficiency of Class-D amplifiers.

Features
➤ Class-T architecture
➤ Single Supply Operation
➤ “Audiophile” Quality Sound
   ➤ 0.05% THD+N @ 13W 4Ω
   ➤ 0.1% THD+N @15.5W 4Ω
   ➤ 0.1% IHF-IM @ 1W 4Ω
➤ High Power
   ➤ 25W @ 4Ω, 10% THD+N, VDD=14.6V
   ➤ 23.5W @ 4Ω, 10% THD+N, VDD=14.2V
   ➤ 14W @ 8Ω, 10% THD+N, VDD=14.2V
➤ High Efficiency
   ➤ 88% @ 13.5W 8Ω
   ➤ 81% @ 25W 4Ω
➤ Dynamic Range = 100 dB
➤ Mute and Sleep inputs
➤ Turn-on & turn-off pop suppression
