PT2317B Digital Preamp Circuit

Digital Preamp Circuit PT2317B. According to the project assignment has to be an amplifier equipped with offsets to low and high tones, and according to the application requirement, it shall be possible to adjust the volume ratio between the left and right channels, thus setting the balance. An essential part is also a volume setting.

Complete Speaker Protection Circuit

Transistor protection circuit for the amp speaker I’ve shared before, “and led Delayed-Exciting DC Speaker protection circuit” The advanced form of the application is different. with the characteristics of the speaker protection circuit; detects a DC voltage leakage which can damage speakers, the speaker disconnects the amplifier from short-circuit (overcurrent protection), overheating protection and thermostat

IL300 Optical Audio Signal Separator Low-Frequency

Linear optocoupler IL300 One of the diode is part of the output circuit, the other is used as feedback. IL300 optocoupler is suitable for both direct and transfer AC signal with a bandwidth of 200 kHz via a linearity of up to 0.01%. The function is stable in terms of temperature, while the temperature coefficient
