Компоненты Описание : SA2531/2 Single Chip telephone: Using dynamic microphone as Tone ringer

Scope
This Application Note describes how to modify the standard application AN1500A to use a dynamic microphone instead of the standard electret microphone. Additionally, an application is shown, which uses the dynamic microphone as Tone ringer.

Key Features
• Updating existing systems using dynamic handset microphone
• No need for a piezo ringer when using the dynamic microphone as Tone ringer

Компоненты Описание : Tone ringer IC for telephone set

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

Компоненты Описание : telephone Tone ringer with Bridge Diode

The IL2418 is a monolithic integrated circuit telephone Tone ringer with bridge diode,  when coupled with an appropriate transducer, it replaces the electro -mechanical bell. The device is designed for use with either a piezo transducer or an inexpensive transformer coupled speaker to

produce a pleasing Tone composed of a high frequency (fR) alternating with a low frequency (fL) resulting in a warble frequency. The supply voltage is obtained from the AC ring signal and the circuit is designed so that noise on the line or variation of the ringing signal can not affect correct operation of the device.

·  On chip high voltage full wave diode bridge rectifier

·  Low current consumption, in order to allow the parallel operation of the 4 devices

·  Low external component count

·  Tone and switching frequencies adjustable by external components

·  High noise immunity due to built-in voltage-current hysteresis

·  Activation voltage adjustable

·  Internal zener diodes to protect against over voltages

·  ringer impedance adjustable with external components
