SC9270 DTMF Decoder Module for Controlling Devices Using Mobile-ML101

• Working Voltage: 5V DC
• Current: 100mA
• Using IC: SC9270
• Output: DTMF to 4-bit data

Description :

This is an SC9270 DTMF Decoder Module. Using with SC9270 Tone Decoder is a kind of commonly used multi-frequency decode IC. It is a complete DTMF receiver. After it received the DTMF signal, it will divide the signal into high-frequency group and low-frequency group and send the signal to the digital decoder which can figure out the key value then send it to the outside Bus via four lines( Q1, Q2, Q3, Q4) as binary form the module.
