Features

4-channel audio power amplifier IC concept

  • CD 0.13μm Process

Higher toughness process for +B Surge

  • Higher Toughness for Immunity Noise

Easy to design for EMI/EMC/BCI etc

  • Full-time output DC offset detection (TOSHIBA Patent)

The IC can perform full-time DC offset voltage detection at speaker terminals. It is possible to realize a system that prevents the speaker voice coil burning caused by the occurrence of DC offset voltage.

  • Small flat package
  • New Linear High-efficiency AMP “Class-TB”

Temperature reduced approx. 20-40 degrees C compared with other AMPs.

  • 6V cruising design
  • Diagnosis function

Toshiba’s original linear high-efficiency amplifier: Class-TB achieves efficiency TCB701FNG(50 W)/702FNG (45 W)

High efficiency (TOSHIBA Patent)

Power dissipation comparison

  • vs Conventional Class-AB AMP >>> -80% reduction
  • vs Digital Class-D AMP >>> Closer under Pout <4 W
Low BOM costs

Reasonable external parts

  • vs Conventional Class-AB AMP >>> Same 
  • vs Digital Class-D AMP >>> Less than half 
Full-time output DC offset detection (TOSHIBA Patent)
  • The IC can perform full-time DC offset voltage detection at speaker terminals. It is possible to realize a system that prevents the speaker voice coil burning caused by the occurrence of DC offset voltage.
