Products

Anaview has developed custom class d audio amplifier systems for leading audio companies all over the world. The products usually contain both power supply and amplifiers and are designed to meet the toughest requirements regarding audio performance, safety, robustness and EMI. Prodcuts have been developed for companies in many different segments.

-          PA amplifiers up to 3500W/4ohm

-          High End HiFi with world leading performance

-          OEM Automotive

-          Aftermarket automotive

-          Industry, Inductive loop amplifiers for trains

Anaview uses proprietary technology which is patent pending. With this technology world leading audio performance can be achieved with very few components and very low idle consumption. One of the difficulties with class d amplification has always been to keep the distorsion low while maintaining a large bandwidth. With Anaview's patent pending APC technology it is possible to reach up to 120kHz -3dB point at the same time as industry leading distorsion and noise figures are presented. The following graphs shows a fully balanced 600W/4ohm amplifier based on APC.

Unique Anaview control IC
Anaview has developed an optimized IC to control the developed amplifiers. This IC is state of the art and it has several unique features.

• Up to 600W/4ohm capability
• Loss less over current protection
• Low propagation delay <100ns
• Matched dead time
• Two mode over current protection, constant current – burst mode

The two mode over current protection makes the amplifier behave as if it is voltage clipping which gives a lot less harmonic content than the traditional burst mode behaviour. The allowable time during constant current mode is settable and so is the time before it tries to restart.
