The LT
1684 is a telecommunication ring tone generator.
The IC takes a user-generated pulse width modulated
(PWM) input and converts it to a high voltage sine wave
suitable for telephone ringing applications.
The LT1684 receives capacitor-isolated differential PWM
input signals encoded with desired ring output cadence,
frequency, and amplitude information. The LT1684 nor-
malizes the pulse amplitude to
±1.25V for an accurate
signal voltage reference. The cadence, frequency and
amplitude information is extracted using a multiple-
pole active filter/amplifier, producing the output ring tone
signal.
The LT1684 uses its own ring tone output as a reference
for generating local supply rails using complementary
high voltage external MOSFETs as dynamic level-shifting
devices. This “active tracking” supply mode of operation
allows linear generation of the high voltage ring tone
signal, reducing the need for large high voltage filtering
elements.
