    A/D-D/A Converter Circuit

    Bu dc-dc dönüştürücüde, 555, TI'nin birincil sargısında yükselen ve çöken bir alan üretmek için kullanılır ve TI'nin ikincil sargısında yüksek bir voltaj üretir. Bu voltaj daha sonra tam dalgadır, köprü Dl ile D4 arasında doğrultulur ve C3 ile filtrelenir. T1, birincil için #26 tel ve ikincil...

    Voltage-to-frequency-converter

    This circuit can accept positive or negative or differential control voltages. The output frequency is zero when the control voltage is zero. The 741 op amp forms a current source controlled by the voltage Ec to charge the timing capacitor C1linearly. NE555 is connected in the astable mode. so...

    V-F converter LM324

    Here we're going to make a V-F converter. What do you think V and F stand for? Not so difficult, V for voltage and F for frequency. So a V-F converter is a device to convert a voltage to a frequency. The schematic shows you that U1:A is an integrating circuit and outputs an integrated voltage...

    12V to 9V DC Converter Circuit Diagram (PCB)

    12V to 9V DC Converter This 12V to 9V DC converter is very useful to power 9V DC devices in a car that uses a 12V DC battery. The maximum current consumption allowed by this circuit is 0.8 amps. This 12V to 9V DC converter is implemented using a zener diode and a NPN bipolar transistor (Q1) as...

    RS485 to RS232 converter

    RS485 is an alternatve for RS232 for long distances. Maximum length of the cable for RS232 is only 15m. For RS485 it is about 1200m. In addition you can connect many devices to RS485 bus (unlike RS232 — only 2). Send/receive mode is selected by RTS signal. The converter was designed to be as...

    Automotive 12V to +-20V converter (for audio amplifier)

    The limitation of car supply voltage (12V) forces to convert the voltages to higher in order to power audio amplifiers. In fact the max audio power x speaker (with 4 ohm impedance) using 12V is (Vsupply+ - Vsupply-)^2/(8*impedance) 12^2/32 = 4.5Watts per channel, that is...
