It is mainly used in circuits where a tone has to be played as a notification for the user. This IC, with its three legs, looks like a transistor. The circuit should not be run in Rechargeable battery also if the Speaker resistance is less than 8 Ohm and may burn the Transistor.

Like Admin has stated, UM66 is designed and manufactured with those melodies. These frequencies are a factor of the oscillator frequency.

UM66T is a melody integrated circuit. We have other Tone Generator circuits that you may like; Take a look: SPI Module of Arduino.

The device has very low power consumption. I will add a voice recorder circuit soon. What can be done to strengthen the multiplier circuit?

Melody Generator using IC UM66

You can not reprogramme it. Previous post Next post. I think the explanation i gave is enough to understand the circuit. Touch Controlled Musical Bell.

Connection Diagram The connection diagram is datsheet below. It can also be easily interfaced with a normal Piezo electric speaker even buzzer or to a 6 ohm speaker through a NPN transistor as shown below.

Do remember that this IC will be able to play only one tone, if you need a different tone you have to use a different IC with a different part number as shown above.

The BT66T can operate only below voltage range 3. Thanks for the CMOS technology. Assemble the circuit on a good quality common board. It is better that you should not run this circuit in Eliminator as most of the available eliminator don’t have a good filter built in and have no precision over voltage protection. Virgin Galactic — Commercial Space Flight. TL — Programmable Reference Voltage.

This high-density System-in-Package SiP integrates controller, power switches, and support components. Capacitor C1 is meant for noise suppression. Ding Dong Sound Generator.

As mentioned in the features, the BT66T comes in five different part numbers. The melody will be available at pin 3 of UM66 and here it is amplified by using Q1 to drive the speaker. Is capacitor helps in sound suppression in this circuit? This is the output pin, where tone is generated. Many versions of UM66T are available which generate tone of different songs. This IC is easy to use because it can work on low voltage 0.

In this circuit please don’t give the supply beyond 3 volt without.
