1. The TAS5630D Class Amplifier Can Be Driven Under DC 48V 4 Load And Can Provide 300W+300W Stereo Output Power. They Use Purepath HD Technology And Ti's Advanced Closed-Loop Architecture To Realize Generation Of Blu-Ray Home Theater Systems, Stand-Alone Home Theaters, And Professional High-Definition Media Playback And Ultra-Low Distortion For Audio Systems. 2. It Is Currently The Most Advanced Digital Power Amplifier 3. This Is A Flagship Digital Power Amplifier With Excellent Analysis And Details, Very Powerful Driving Force, And Very Low Power Consumption. 4. This Board Is A Finished Board And Can Be Used As Soon As It Is Powered On. 5. Rectifier And Filter Capacitors, The Filter Capacitor Should Not Be Less Than 22000uf, Otherwise The Impure Power Supply Will Affect The Signal-To-Noise Ratio. In Addition, It Is Best To Connect Exposed Components Such As Potentiometers And Shield Them, And Make Them As Quiet As The According To Specifications. 1.Total Harmonic Distortion (+N):Less than 1% 2. Signal-To-Noise Ratio (): 100DB 3. Input Impedance: 20K 4.Output Offset Voltage:Less than 150MV 5.Voltage Gain: Adjustable 6. Slew Rate (): 50V/USs 7. Frequency Response Range: 20HZ--20Khz 8. Power Supply Range: DC20--DC50v (20-45V Range Recommended, Not Recommended For Use Under The Extreme Voltage Of 48-50V) 9.Pcb Size: About 101.6x98.5mm 10. Precautions For Use: This Board Is Powered By Dc. Do Not Input Ac Directly. Use An Ac Transformer And Plug In An External Rectifier Bridge And Filter Capacitor. In Addition, The Dc Power Supply Should Not Exceed 50V, Nor Be Lower Than 20V. If It Is Lower Than 20V, It Will Not Start. In Addition, The Output Power Is Related To The Power Of The Power Supply. The Power At 50V Will Be More Than 4 Times That At 20V. 11.Colour:As Shown 12.Material:PCB Note: Different Batches May Have Differences In Product Appearance, Color, And Printed Characters, Which Will Not Affect The Use Package Contents: 1 x Digital Amplifier Board 1 x Connecting Cable Only the above package content, other products are not included.
