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

The CS9370DGP is a highly integrated Dual Tone Multi Frequency (DTMF) receiver. It combines digital decoder and bandsplit filter functions into a single chip. This advanced IC utilizes digital counting techniques for precise tone detection. It can accurately decode all 16 standard DTMF tone pairs. The output is a convenient 4-bit code, simplifying integration. 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 wide operating voltage and low standby current for versatile applications. The CS9370DGP ensures excellent performance in various communication systems.
