<p>1. TDA7498 Is The First 100W+100W Amplifier Currently On The Market, Which Supports Single-Chip Integrated Analog, Logic And High-Voltage Functions.</p> <p>2. Compared With Other Class D Amplification Processes That Create Higher Chip Area Energizers, Stmicroelectronics'Bcd6s Has A Higher Efficiency Ratio While Also Reducing Crosstalk And Improving Sound Quality.</p> <p>3. In Addition, The Bcd6s High-Power Output Circuit Integrates Nmos And Pmos Complementary Transistors, Eliminating The Need For Bootstrap Capacitors And Cathode Load Diodes Required In The Old Process. The Distortion (+N) Of Stmicroelectronics Tda7498 Is Less Than 0.01%, Which Can Provide A Higher Quality Listening Experience.</p> <p>4. Use for-Original TDA7498, And The Electrolytic Capacitor Is From A Famous With A Capacity Of 2200uF, Ensuring Strong And Continuous .</p> <p>5. The Resistors Use High-Precision 0805 Chip Resistors, And The Main Circuit Uses Five-Ring Metal Film Resistors With An Accuracy Of 1%, Ensuring A Good Signal-To-Noise Ratio Of The Whole Machine.</p> <p>The PCB Uses 1.6mm Thick Double-Sided Sheets, 2.0 OZ Copper Thickness, And Full Tin Spraying Process To Good Passing Performance Of Large And Small Currents.
