The TMS8020 is a mono filter-less class-D amplifier with high SNR and differential input that eliminate noise. With an alternative option between Class-D and Class-AB output, which makes the device very ideal for efficiency-EMI compatible applications.

Features like higher than 90% efficiency and small PCB area make the TMS8020 class-D amplifier ideal for portable devices. The filter-less architecture requires no external output filter, fewer external components, less PCB area and lower system costs, and simplifies application design. Integrated NCN technology suppresses output automatically improving the sound quality and helping to protect the speakers.

With the soft-driving technology, the edge of the PWM at output stage is very flat which is very useful for EMI suppressing.

The TMS8020 features short circuit protection, thermal shutdown and under voltage lock-out.

The TMS8020 is available in DFN2x2-8 and MSOP8 green packages.
