ELM701
Solid State Mouse
Description
The ELM701 is a fun circuit for creating mouse- like noises. Its very low current consumption makes it an ideal candidate for battery-powered toys and novelty items.
All of the logic required for circuit operation is contained within this 8 pin integrated circuit. Normally only a battery, a piezo element, and a single resistor are all that are needed for a complete circuit, although an on/off switch may be desireable.
The ELM701 uses pseudo-random number generators to produce from one to four ‘chirps’ at random intervals of up to about eight seconds. This makes the noises seem more like a real (but fairly active) rodent. Between these series of chirps, the circuit reverts to low power mode in order to conserve battery energy.
Applications
- Mousetrap bait
- Unique power on warning
- Voicing for toys
- Coffee machine or office desk item
- A fun plaything
Features
- Low power CMOS design
- Wide supply range – 3.0 to 5.5 volt operation
- Low power mode between chirps saves batteries
- Pseudo-random intervals for more realistic sounds
- Push-pull piezo drive eliminates the need for an external capacitor while providing high volume
- Only one external resistor required
