CS9370DGP DTMF Decoder Chip - Dual-Tone Multi-Frequency Receiver IC

The CS9370DGP is an advanced Dual Tone Multi Frequency (DTMF) receiver IC. It integrates both digital decoder and bandsplit filter functions into a single chip. This IC precisely detects and decodes all 16 standard DTMF tone pairs using digital counting techniques. Its convenient 4-bit output simplifies integration into various systems. High-accuracy switched capacitor filters efficiently separate low and high group signals. A built-in dial tone rejection circuit eliminates the need for external pre-filtering. This design minimizes external components, saving board space and cost. It offers a wide operating voltage and low standby current, ensuring versatile applications. The CS9370DGP delivers excellent performance for telecommunication and control systems.
