LC7387 is a DTMF (Dual-Tone Multi-Frequency) receiver IC manufactured by SANYO.

The LC7387 is a DTMF (Dual-Tone Multi-Frequency) receiver IC manufactured by SANYO. Below are its key specifications, descriptions, and features:

Specifications:

  • Supply Voltage: 2.5V to 5.5V
  • Operating Current: 1.5mA (typical at 3V)
  • Standby Current: 0.5μA (typical)
  • Operating Temperature Range: -20°C to +70°C
  • Package Type: SOP-16 (Small Outline Package)
  • DTMF Decoding: Supports all 16 standard DTMF tones
  • Frequency Tolerance: ±1.5% (typical)
  • Input Gain Control: Automatic gain adjustment

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.
