TA2020 Datasheet PDF – Digital Audio Power Amplifier

Part Number: TA2020, TA2020-020

Function : STEREO 20W (4Ω) Class-T Digital Audio Power Amplifier IC

Package: 32-pin SSIP type

Manufacturer: Tripath Technology




The TA2020 is a 20W (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.




1. Class-T architecture
2. Single Supply Operation
3. Dynamic Range = 99dB
4. Mute and Sleep inputs
5. Turn-on & turn-off pop suppression
6. Over-current protection
7. Over-temperature protection
8. Bridged outputs

Benefits :

1. Fully integrated solution with FETs

2. Easier to design-in than Class-D

3. Reduced system cost with no heat sink

4. Dramatically improves efficiency versus Class-AB
