      MC33219AP DIP24 (MOTOROLA) Voice switched speakerphone

       

      The Motorola MC33219A Voice Switched Speakerphone Circuit
      incorporates the necessary amplifiers, attenuators, level detectors, and
      control algorithm to form the heart of a high quality hands–free
      speakerphone system. Included are a microphone amplifier with mute,
      transmit and receive attenuators, a background monitoring system for both
      the transmit and receive paths, and level detectors for each path. An AGC
      system reduces the receive gain on long lines where loop current and power
      are in short supply. A dial tone detector prevents fading of dial tone. A Chip
      Disable pin permits conserving power when the circuit is not in use. The
      volume control can be implemented with a potentiometer.
      The MC33219A can be operated from a power supply, or from the
      telephone line, requiring typically 3.2 mA. It can be used in conjunction with a
      variety of speech networks. Applications include not only speakerphones,
      but intercoms and other voice switched devices.
      The MC33219A is available in a 24 pin narrow body DIP, and a wide body
      SOIC package.
