MC34018LINEAR INTEGRATED CIRCUIT
VOICE SWITCHED SPEAKER-PHONE CIRCUIT

DESCRIPTION
 
The UTC MC34018 speaker-phone integrated circuit includes all the active circuitry and control functions to implement a high
quality hands-free telephone system. The circuit includes a microphone amplifier, a speaker amplifier, level detectors, a background sound level monitoring system in both the transmit and receive channels and an attenuation system which can control the transmit and receive levels as well as the background level.
The applications include household and office speaker-phones, intercom systems, hand free kit for mobile phones, and others.
 
FEATURES
  • Chip Select pin for Power conservation (active/standby mode).
  • Integrated all necessary active circuitry for a hand-free telephone into one single chip.
  • Operating under wide dynamic range through signal compression technology.
  • Build-In voltage regulators illuminate external regulators for lining operation.
  • Monitoring system for background noise level.
  • Background sound level compensation for transmit and receive levels as well as the background level.
  • Power audio amplifier for typical 100mW output (into 25Ω) with peak limiting for speaker to minimize distortion.
  • Volume control function for external volume control circuit.

MC34018 線性集成電路
語音切換揚聲器電話電路

描述
 
UTC MC34018揚聲器電話集成電路包括所有有源電路和控制功能，可實現高音質
優質的免提電話系統。該電路包括一個麥克風放大器，一個揚聲器放大器，一個電平檢測器，一個在發射和接收通道中的背景聲級監視系統以及一個可以控制發射和接收級以及背景電平的衰減系統。
這些應用包括家用和辦公室揚聲器電話，對講系統，手機免提套件等。

特徵
  • 片選引腳，用於省電（活動/待機模式）。
  • 將免提電話的所有必要有源電路集成到一個芯片中。
  • 通過信號壓縮技術在寬動態範圍內運行。
  • 內置穩壓器為襯砌操作照亮外部穩壓器。
  • 監測系統的背景噪聲水平。
  • 用於發送和接收電平以及背景電平的背景聲電平補償。
  • 功率音頻放大器，用於典型的100mW輸出（25Ω），峰值限制用於揚聲器，以最大程度地減小失真。
  • 外部音量控制電路的音量控制功能。
