LME49830+K1530/J201 300W Mono Power Amplfier Board High-end Pure Class
LME49830 chip main parameters:
- Wide voltage range of +-20V to +-100V
- Slew Rate 39V/μs
- Driving Current 60mA (typ)
- PSRR (f = DC) 105dB
- Total harmonic distortion + noise (f = 1kHz) 0.0006
Amplifier board design features:
- Driver MOSFET Toshiba original 2SK2013/2S313
- Current output stage with three pairs of Toshiba 2SK1530/2SJ201 FET, low output impedance, power margin large, closer to the ideal amp;
- A perfect mid-point voltage protection circuit, speaker delay protection circuit, the main chip used in J- apan produced UPC1237, the IC is stable and reliable.
- Voltage level / current power supply separate from the design stage, so that when the current level of large dynamic fluctuations in the power level of the former to minimize coloration.
- Double-sided PCB design 2mm glass plate, 1% precision metal film resistors, capacitors mica United States, Germany Wima capacitors, high voltage electrolytic capacitors Ruby Japan, all thecomponents to ensure that new imported
