Part number: TDA8954TH
Description:
The TDA8954TH is a2 channel audio power amplifier which uses the class D technology for the power amplification. The audio signals are converted into pulse width modulation, TDA8954TH is a class D mono high-efficiency or stereo power amplifier with a single designed low power dissipation. The combined audio frequency of class D with audiophile sound quality is associated with the classification of AB amplifiers. It is supplied with diagnostic pins configuration for the monitoring status of fold black and other elementary component protection circuits.
Features and Specifications :
- It is 2-pin diagnostic for protection of circuits
- The TDA8954TH has zero dead time switching
- Available with BD modulation in BTL configuration
- The current switching and quiescent is low
- Fabricated and consists thermal Fold Black with disable functionality
- Consists of a smooth pop noise free start-up and switch off functioning
