tda1591 stereo decoder schematic

This circuit will detect AC line currents of about 250 mA or more without making any electrical connections to the line. Current is detected by passing one of the AC lines through an inductive pickup (L1) made with a...

A simple 12V battery charger circuit can be designed using a TIP3055 power transistor to limit the current to the battery. The circuit turns off when the battery voltage reaches approximately 14V or if the current exceeds 2A. This...

This sound level meter serves as an excellent one-chip alternative to traditional analog meters. It is entirely solid-state, ensuring durability and longevity. The circuit is based on the LM3915 audio level integrated circuit and requires only a minimal number...

This circuit enables the testing of a servo motor. The angle of the servo can be adjusted using a 10k potentiometer. It is possible that not all positions can be achieved with this circuit; experimenting with different resistors may...

Very simple and useful circuit for amplify the stereo signals. The circuit dissipates roughly 28 watts of heat, so a good heatsink is necessary. The chip should run cool enough to touch with the proper heatsink installed. The circuit...

It is advisable to enclose this circuit in a box and label each LED with numbers from 1 to 6. When switch S1 is momentarily pressed, one of the six LEDs will illuminate, with the number corresponding to the...
