    DTMF Decoder 
     

    Decodes DTMF audio signal to 4 bit binary TTL level output with LED indication. Suitable for use with microcontroller applications.


    Features 
    · Decodes DTMF as 4 bit binary
    · TTL level output for direct connection to microcontrollers
    · Low power 5V DC operation
    · LED indication of outputs
    · Simple to use
    · Based on excellent HT9170B IC

    Applications

    · Remote Control systems
    · Caller ID applications
    · FM receiver based remote control
    · Remote control using Mobile phone

    Specification 

    Operating Voltage 5 V DC Regulated power supply input
    Operating Current 100 mA

    Information
     

    Connect regulated +5V DC supply for operation of board. Outputs Q1-4 and VT are active high output at 5V level. If any LED is on means that output is at high level. VT LED blinks once a new DTMF tone is received. The binary data appears at Q1 to Q4. Details of this output is on next page.Input signal can be from an audio source like microphone amplifier, FM radio receiver, wired phone line. Please note when connecting land line phone signal, do not connect ground wire of board to phone line directly. Use a 100nF capacitor in series to phone line wires at ground.

     

    Applications :

     

    1) Mobile Controlled Robot

    2) Home Automation

    3) Lights On/Off Through Your Mobile Phone
