Descriptions:

The LC7387 is a low-power DTMF receiver IC designed for decoding telephone keypad tones. It integrates a band-split filter and digital decoding circuitry to accurately detect DTMF signals. It is suitable for applications such as telecommunication systems, remote control, and security systems.

Features:

• Low Power Consumption: Ideal for battery-operated devices.
• Built-in Band-Split Filter: Eliminates the need for external filters.
• Auto Gain Control (AGC): Ensures reliable decoding under varying signal levels.
• Digital Counting Technique: Provides high noise immunity.
• Standby Mode: Minimizes power consumption when inactive.
• Simple Interface: Directly outputs decoded 4-bit binary data.
