U should be careful while drawing the circuit. Hi buddy there is basic flaw in circuit.

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

The zener diode is connected directly to the 9 volt supply. Quote and Order boards in minutes on https: It is a low cost and low powered 8 pin IC.

With some basic mistakes just as in your circuit the beginners will get disheartened when there ckt doesn’t work. It is a low cost and low powered 8 pin IC.

Below is the table for 4 Playing modes, you can produce whatever sound you want. We can change the frequeccy by rotating the knob of variable resistor. There should be a resistence of 1K. Get Our Weekly Newsletter! It has inbuilt oscillators and circuitry to produce the sounds, and only require one external resistor. 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 some kind of alerting sound.

UM Pin diagram and Pin description is given below, taken from its Datasheet:. 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 has inbuilt oscillators and circuitry to produce the sounds, and only require one external resistor. As we have used 9v battery, so we have used Zener Diode 3.

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

UM Pin diagram and Pin description is given below, taken from its Datasheet:. As we have used 9v battery, so we have used Zener Diode 3. Hi buddy there is basic flaw in circuit. It is generally used in alarms and toys.

Below is the table for 4 Playing modes, you can produce whatever sound you want. UM Pin diagram uk3561 Pin description is given below, taken from its Datasheet: U should be careful while drawing the circuit. UM Pin diagram and Pin description is given below, taken from its Datasheet: There should be a resistence of 1K.

Quote and Order boards in minutes on https: Leave Open for Normal Operations.

This voltage is called Breakdown Voltage or Zener Knee voltage. The zener diode is connected directly to the 9 volt supply. Zener Diode is just like the other diodes, with only one difference.

UM UMA Audio IC

Leave Open for Normal Operations. 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.

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. 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. While building circuits datashdet times we need to generate sounds like a musical sound or some kind of alerting sound.

This voltage is called Breakdown Voltage or Zener Knee voltage. Log in or register to post Comment.
