TDA8929T TDA8927J Klasse-D Verstärker Schaltung Projekt Klasse-D-Verstärker TDA8927J Diese integrierte Schaltung enthält einen terminal-switching-transistoren type DMOS (Double-Diffused MOS), schaltungen für die Ansteuerung der transistoren und schaltkreise für die Kommunikation mit dem control-Schaltung. Es ist auch ausgestattet mit einem Kontroll-Schaltung für die Erkennung der maximale Ausgangsstrom und Temperatur-sensor. Weitere, diese Schaltung zeichnet sich durch hohe Effizienz, einen relativ großen Bereich der Versorgungsspannung, ein kleines stocken Schock und wie bereits erwähnt, es enthält auch Thermoschutz und Schutz gegen Kurzschluss der Ausgangsklemmen. TDA8929T Diese integrierte Schaltung enthält (für zwei audio-Kanäle), zwei pulse-width-Modulatoren (PWM), zwei analoge feedback-Schleifen und zwei Eingangs-differenzverstärker. Des weiteren enthält schaltungen gemeinsam für beide Kanäle, wie den Oszillator, alle Bezugsquellen und Regelkreise.
