180W + 180W Power Supply Audio Power Amplifier ICs

Overview: The STK412-000 series are class H audio power amplifier hybrid ICs that feature a built-in shift power supply circuit. These ICs provide high efficiency audio power amplification by controlling (switching) the supply voltage supplied to the power transistors according to the detected level of the input audio signal.  Features: Pin compatible IC series that covers power ratings from 50 W × 2 channels to 180 W × 2 channels at 0.7 or 0.8% THD, 20 Hz to 20 kHz. This allows the use of a common PCB for all output classes.  The pin arrangement is also unified with that of the three-channel STK413-000 series. This means that PCBs designed for three-channel models can also be used for two-channel models.  Miniature package — 50 W/ch to 120 W/ch (THD = 0.8%, f = 20 Hz to 20 kHz): 64 × 36.5× 8.5 mm* — 150 W/ch to 180 W/ch (THD = 0.7%, f = 20 Hz to 20 kHz): 78 × 44× 9 mm* * Not including the IC pins.  Allowable load shorted time: 0.3 s Circuit Diagram: ...

How to Build a Subwoofer Box

Building a subwoofer box is the foundation of your new car audio system . In this video I will show you different techniques that will make your sub enclosure perfect and help it sound even better! How to Build a Subwoofer Box

300W Building a subwoofer enclosure

This is how a subwoofer enclosure is built, it is ported and is tuned to 35hz the subwoofers that i am installing are 2 re 8's that are dual voice coil and i am pushing 300watts at 4ohms. 300W Building a subwoofer enclosure

7 segment display Arduino

The aim of this article demonstrate how the Arduino can run on 7-segment display.   We used a SA56-11GWA which is a single display with common anode, it means that the anode is common to all digits, and to the point. A display consists of 8 LEDs, 7 form the figure and 1 point decimal.A conversion between decimal and what we intend to show the binary information that you receive is called the BCD (Binary Coded Decimal). In terms of hardware, each LED work individually, so each of the segments has to lead a limiting resistor, in this case, each digit has an operating voltage of 2.2V and consumes 20mA.   If the voltage is 5volts, we need the resistor fall 5-2.2 = 3.8V, by Ohm's Law we can calculate, R = V  res  / I  led  R = 3.8 / 0.020 = 190 Ω +/- 20% (let's use a resistor with 220Ω).   This applies to this display SA56-11GWA used as an example, other values ​​may be different, it is useful to calculate the required resistance value.
