LM4766T 2 x 40W DC Servo Current Stereo Terminated Amplifier Board 25 ± 30V

Description

LM4766T 2 x 40W DC Servo Current Stereo Terminated Amplifier Board 25 ± 30V
Product introduction:
LM47666 is a high-quality bile sound 2×40W power amplifier integrated circuit introduced by the US National Semiconductor Corporation (NS) at the end of 1995. It is 15-pin package and safe and convenient to use. It has NS patented SPIKE instantaneous temperature loss protection circuit, overvoltage and ow Voltage, overload protection, and monitoring transistor safe working area protection function, fade in and fade out the squelch mode. Shielded wires should be used for the input lines to further improve the signal-to-noise ratio. The internal resistance of the power supply should be small, and sufficient power reserve must be reserved to prevent chipping distortion and overload distortion during large dynamics. Circuit parameters are subject to change without notice.
Product manual:
The 5532 bipolar op amp DC servo constant current type power amplifier board is used, the switching machine is quiet, better than the voltage feedback type high and low frequency extension, the treble is crisp and bright, the cord is smooth, the bass is powerful, flexible, and more daring. .
