Technical topics
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
Temperature data of Class-AB/TB AMP
Test Condition
Vcc=13.2V, f=1kHz, RL=4Ω, Pout=0.4W x 4ch operated, Ta=25℃,
Heat sink Thermal resistance : 6.5℃/W (Size : 85×85×2mm at Aluminum)
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.
