Tone ringer IC for telephone set

Tone ringer

This IC is a Tone ringer for generating bell sound from call signal.

Features
1) Absolute maximum supply voltage 40V
2) High output level
3) Pincompatible with Ba6565A, ML8205

Applications
   telephone, ITS, TAM, FAX, etc.

DESCRIPTION
THE KA2410/2411 IS A BIPOLAR INTEGRATED CIRCUIT DESIGNED for telephone Tone ringer.THESE DEVICES CONSISTS OF AN OUTPUT AMPLIFIER, TWO OSCILLATORS, AND POWER SUPPLY CONTROL CIRCUIT.

FEATURES
♦ Low current drain
♦ Adjustable 2 Tone frequency
♦ Hysteresis circuit prevents false triggering and rotary dial “CHIRPS”
♦ 8 pin DIP plastic package
♦ External triggering or ringer disables (KA2410)
♦ Adjustable for reduced supply initiation current (KA2411)

APPLICATIONS
♦ telephone bell replacement
♦ Extension Tone ringer modules
♦ Alarms or other alerting devices

The BA8206 and BA8206F are Tone ringer ICs which produce a bell sound from a ringing signal. The frequency of the bell sound can be varied by changing the constants of the external resistance and capacitors. The operation initiation current dissipation can be changed at the RSL pin. Also, the output load can be selected, as a piezoelectric buzzer, a transformer coupled speaker, or other similar devices.

Features
1) Low current dissipation.
2) Withstands up to 40V.
3) Operation initiation current dissipation can be changed using RSL pin.
4) Pin layout is compatible with the BA8205, BA6565A, and ML8205.
Applications

Applications
   telephones, multi-function telephones, telephone answering machines, facsimiles, equipment involving telephones
