TECHNICAL DATA
IL6840
Telephone Tone Ringer with
Bridge Diode
The IL6840 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.

This device contains protection circuitry to guard against damage due to high static voltages or electric fields.
However, precautions must be taken to avoid applications of any voltage higher than maximum rated voltages to this
high-impedance circuit. For proper operation, VIN and VOUT should be constrained to the range GND≤(VIN or
V
OUT)≤VCC.
Unused inputs must always be tied to an appropriate logic voltage level (e.g., either GND or VCC). Unused
outputs must be left open.

DESCRIPTION
The IL6840 tone ringer derives its power supply by rectifying the AC ringing signal. It uses this power to activate
two tone generators. The two tone frequencies generated are switched by internal oscillator in a fast sequence and made
audible across an output amplifier in the loudspeaker; both tone frequencies and the switching frequency can be
externally adjusted.
The device can drive either directly a piezo ceramic converter (buzzer) or small loudspeaker. In case of using a
loud-speaker, a transformer is needed.
An internal shunt voltage regulator provides DC voltage to the output stage, low frequency oscillator, and high
frequency oscillator. To protect the IC from telephone line transients, a zener Diode is included.
