Features

  • Low current consumption.
  • Integrated rectifier bridge with zener diodes for overvoltage protection.
  • Minimum external circuitry.
  • Both frequencies of tone and switching are adjustable by external
  • components.
  • Integrated voltage and current hysteresis.

The UTC LS1240A ringer IC is designed to drive a piezo-ceramic converter(buzzer) directly.

For driving a dynamic loudspeaker the UTC LS1240A needs only a decoupling capacitor to replace the usual transformer usage.

The output stage of UTC LS1240A will drive a minimum load of 50 ohms.

The two tone frequencies generated are switched by an internal oscillator in fast sequence. Both tone frequencies and the switching frequency can be externally adjusted.
