UM3561 Siren Sound Generator COM22

It is a low cost and low powered 8 pin IC. While UM66 have a limitation of generating only one sound, we have UM which is very useful and can generate four types of sound i. With some basic im3561 just as in your circuit the beginners will get disheartened when there ckt doesn’t work. It has inbuilt oscillators and circuitry to produce the sounds, and only require one external resistor.

Quote and Order boards in minutes on https: It is generally used in alarms and toys. All the diodes allow flow of current in only one direction forwardbut Zener diode can allow current in reverse direction dataaheet the voltage goes beyond a certain limit.

UM Datasheet, PDF – Alldatasheet

Zener Diode is just like the other diodes, with only one difference. While building circuits many times we need to generate sounds like a musical sound or some kind of alerting sound.

UM Pin diagram and Pin description is given below, taken from its Datasheet:. UM Pin diagram and Pin description is given below, taken from its Datasheet: We can change the frequeccy datashet rotating the knob of variable resistor.

Leave Open for Normal Operations. As we have used 9v battery, so we have used Zener Diode 3. U should be careful while drawing the circuit. As we have used 9v battery, so we have used Zener Diode 3.

This voltage is called Breakdown Voltage or Zener Knee voltage.

Leave Open for Normal Operations. The zener diode is connected directly to the 9 volt supply. U should be careful while drawing the circuit. The zener diode is connected directly to the 9 volt supply. It is a low cost and low powered 8 pin IC. Get Our Weekly Newsletter! There should be a resistence of 1K. datxsheet

UM works in the range of volts, voltage higher than 5V can damage the IC, so darasheet we are using it with other circuit or using a high voltage source, a Zener diode must be connected, to protect the IC.
