The zener diode is connected directly to the 9 volt supply. Quote and Order boards in minutes on https: UM works in the range of volts, voltage higher than 5V can damage the IC, so if we are using it with other circuit or using a high voltage source, a Zener diode must be connected, to protect the IC. It is generally used in alarms and toys. The zener diode is connected directly to the 9 volt supply. Below is the table for 4 Playing modes, you can produce whatever sound you want.

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

UM Datasheet pdf – Three Siren Sound Generator – UMC

All the diodes allow flow of current in only one direction forwardbut Zener diode can darasheet current in reverse direction if the voltage goes beyond a certain limit. We can change the frequeccy by rotating the knob of variable resistor. Get Our Weekly Newsletter! As we have used 9v battery, so we have used Zener Diode 3.

It is generally used in alarms and toys. With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work. Quote and Order boards in datxsheet on https: The output generated by the IC is not sufficient to drive a 8ohm small speaker, so to amplify the output of the IC, a transistor must be used at the output PIN 3.

With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt dattasheet work. It is a low cost and low powered 8 pin IC. Get Our Weekly Newsletter!

Leave Open for Normal Operations. UM Pin diagram and Pin description is given below, taken from its Datasheet:.

While UM66 have a limitation of generating only one sound, we have UM which is very useful and can generate four i of sound i. Hi buddy there is basic flaw in circuit. It has inbuilt oscillators and circuitry to produce the sounds, and only require one external resistor. UM Pin diagram and Pin description is given below, taken from its Datasheet:.

This voltage is called Breakdown Voltage or Zener Knee voltage. U should be careful while drawing the circuit. While UM66 have a limitation of generating only one sound, we have UM which is very datasheer and can generate four types of sound i. Hi buddy datawheet is basic flaw in circuit. As we have used 9v battery, so we have used Zener Diode 3.

The output generated by the IC is not sufficient to drive a 8ohm small speaker, so to amplify the output datashest the IC, a transistor must be used at the output PIN 3. All the diodes allow flow of current in only one direction forwardbut Zener diode can allow current in reverse direction if the voltage goes beyond a certain limit.

It is a low cost and low powered 8 pin IC. We can change the frequeccy by rotating the knob of variable resistor. While building circuits many times we need to generate sounds like a musical sound or mu3561 kind of alerting sound. UM Pin diagram and Pin description is given below, taken from its Datasheet: There should be a resistence of 1K.

Zener Diode is just like the other diodes, with only one difference.
