Description
LME49830_IRFP240_IRFP9240 with 100W Mono DC Servo FET Power Amplifier Board
●Electrical characteristics:
●Working status: Class A and B (can be adjusted to Class A according to needs)
●Output power: 100W*(4Ω)<* V=±60v>
●Working voltage: ±55V
●Input interface: mono signal input
●Output interface: mono speaker output
●PCB size: 152 x 93.5 mm, PCB thickness 2MM, copper foil thickness 2 ounces
●Power amplifier board design features:
●The current output stage adopts a pair of IRFP240/IRFP9240 field effect transistors, with low output impedance and large power margin, which is closer to an ideal amplifier.
●It has a complete midpoint voltage protection circuit and a horn delay protection circuit. The main chip adopts the UPC1237 produced in Japan. The integrated circuit is stable and reliable.
The midpoint adopts a DC servo circuit and a reasonable PCB layout, so that the midpoint output of the power amplifier board is less than 5MV.
●Double-sided 2mm glass fiber board PCB design, 1% precision metal film resistors, American mica capacitors, German Weimar capacitors, imported audio special high-voltage electrolytic capacitors, all components are guaranteed to be imported with new original packaging, and second-hand goods are eliminated.
●The LME49830 power amplifier board is a single-channel design. Two power amplifier boards are required to form a dual-channel. Each channel adopts a LME49830 + pair of field effect tube design, and the left and right channels have a symmetrical PCB structure.
●Main parameters of LME49830 chip:
●Wide voltage range ±20V to ±100V
●Conversion rate 39V/μs
●Drive current 60mA (typ)
● Power ripple rejection ratio (f = DC) 105dB
● Total harmonic distortion + noise (f = 1kHz) 0.0006
Package：
1pc LME49830_IRFP240_IRFP9240 with 100W Mono DC Servo FET Power Amplifier Board
