Depending on the choice, this IC can easily produce 4 unique varieties of siren audio similar to a gun sound, ambulance siren, police siren, and fire brigade siren. Well, so these were some useful features of IC UM3561 sound generator, which can be implemented as siren generator intended for producing a siren sound in the toy vehicle software. ![]() Idd (Operational minimal Current): 150♚.Vdd (Supply voltage): Minimum -2.4V, Maximum -3.6V, and ideal -3V.storage Temperature range is-55☌ to 125☌.Wide operating temperature range -10☌ to 60☌.Input or Output voltage (Vss) is 3.0V to +3.0V VDD.DC Supply voltage ranges between 3.0V to +5.0V.The technical specs of IC UM3561 range from the following. Low-power CMOS LSI applied to alarm and plaything purposes.The key features of IC UM3561 consist of the following. Moreover, for additional volume of audio, the LM386 amplifier may be used in this particular circuit. Within this circuit, just one transistor amplifier is employed to operate an 8-ohm speaker. The UM3561 can easily operate a piezo without resorting to any kind of stage of amplification. It is ideal for several low voltage programs. The developing of this circuit can be carried out using simple electronic components and a 3V battery pack. For example, the produced sounds can be utilized as alarm circuit, tone generator, and siren circuit etc. This circuit can easily be used for just about any form of audio generation preferences. The 4 diverse siren tones could be produced simply by pushing the 3 buttons like S1, S2 &S3. This is a low-power CMOS integrated circuit. The circuit of 4 siren sound generator using UM3561 IC is indicated below. The UM3561 IC enables you to create circuits just like a Police siren, Fire engine siren, Ambulance siren, and Machine gun sound. Four Siren Sound Generator using UM3561 IC Therefore the sound could be increased with a single NPN-transistor. ![]() Because the audio may be weaker an amplifier is necessary to obtain a high in volume tone. Therefore the produced tone frequency become attainable through the o/p pin-3. The control circuit resources the audio frequency to an address counter & to the ROM. This circuit could be implemented with respect to the selection of music tone via the pin-6 and pin1. This IC contains an oscillator circuit whose frequency could be governed with the resistor attached outwardly to the 1st oscillator or pin7 along with oscillator2 or pin8.Īs a result, the amplitudes that are generated is going to be transferred to a control circuit. The block diagram of IC UM3561 is demonstrated below. Pin-8 (OSC2): External oscillator lead-2Ĭircuit Diagram Tone Selector Configuration.Pin-7 (OSC1): External oscillator lead-1.Pin-6 (SEL1): Allows selection of sound variations pin-1. ![]()
