60 Second Digital Voice
Recorder with Repeat Function - Assembled
With this advanced digital audio
recorder/player, you can record up to 60 seconds of speech or any
other audio with the built-in microphone and later play it back
anytime. This unique design is made possible through the ISD25xx
series of Integrated Circuits which store voice and audio signals
directly, in their analog form, into a 480K Cell Nonvolatile Analog
Storage EEPROM requiring neither analog-to-digital nor
digital-to-analog converter. Recordings stored in this non-volatile
memory cell last up to 100 years and therefore even if the supply
voltage is disconnected, the recording will not be lost.
Another unique feature of this circuit is a message looping mode of
operation which continuously plays back the recorded message
automatically.
The circuit also incorporates a built-in audio amplifier so it can
be directly connected to a speaker or connected to a power amplifier for
greater output power.
Some applications for this circuit include:
Doorbell or entrance message. Greet your guests or customers with a
welcome message.
"Watchdog"
burglar alarm system. Record the barking of a dog and connect this
circuit to a alarm system to deter burglars.
Toys
applications where you need speech or audio effects.
Talking
picture frames for personal or museum use. Add it to the back of a
picture frame of a friend or relative to have his or her voice be
played back at any time.
With the
looping mode of operation, you can connect the circuit to one of our
FM Transmitters in order to build a FM Announcement System or
talking
sign which is ideal for real estate applications.
