ขาย แผงวงจร5128 Mini Class Ab โมดูลขยายเสียงดิจิตอล 5v Mono 5 W Audio Power Amplifier ราคาที่ดีที่สุด

Product parameters Product Name: Mono Digital Power Amplifier Module Load range: impedance 2 8 ohms, power 3-50W speaker Working voltage: DC2.5-5.5V Working current: 1A or more Output power: 3- 5W Finished product specification: 20x 16x15mm (length x width x height) Product net weight: 2.5g Overview The LTK5128 is a 5W, mono Class AB/Class D mode switching function, ultra low EMI, filterless audio power amplifier chip. The LTK5128 can be easily switched to Class AB mode with a MODE pin to eliminate EM interference. Operating voltage 2.5V-5.5V, can provide more than 90% efficiency in Class D amplifier mode, the new filterless structure can eliminate the traditional low-pass filter of Class D amplifier, thus saving system cost and IPCB Space is ideal for portable applications. The LTK5128 uses the unique DRC (Dynamic range control) technology to reduce the distortion caused by waveform chopping at high power output, and the dynamic response is better than similar products. The LTK5128 is available in an SOP-8 package. Characteristics Filterless Class D / Class AB amplifier, low quiescent current and low EMI FM mode without interference Excellent blasting sound suppression circuit Low noise, low distortion DRC dynamic distortion correction circuit 10% THD+N, VDD=5V, up to 3W output power at 4Q load 10% THD+N, VDD=5V, up to 5W output power at 20 loads Short circuit current protection Undervoltage protection Shutdown current <0.5uA Multiple power package modes: ESOP-8 Overheating protection application Bluetooth Speaker Trolley speaker, USB audio Video machine, loudspeaker, etc. We deal in wholesale and retail Feel free to contact us #5128 #Amplifier #Board
