DTMF Decoder IC

MT8870DS1 Allgemeine Beschreibung

The MT8870DS1 is a versatile DTMF decoder IC that offers reliable and efficient decoding of dual-tone multi-frequency signals. With its advanced digital counting techniques, this integrated circuit is able to accurately detect and decode all 16 DTMF tone pairs into a 4-bit code. Its on-chip oscillator and low-power standby mode make it energy-efficient, while the digital filtering algorithm ensures accurate tone detection by eliminating false signals caused by noise

Mancando instructions, was not immediate use. When arrive is set so "adjust". If you want it to fixed voltage is cut off the track at the top. But also by putting it to fixed voltage, is not accurate: set to 5 V NE forniva 4,93. I put adjust and then I adjusted the output to 5 V.
