Abstract

See full text

A ring detect/Caller I.D. detect circuit employs first and second operational amplifiers supplied with a differential input from the AC side of a diode bridge. The differential input is converted to a single ended input supplied in a first mode to a ring detect comparator supplied with a plurality of selectable reference voltages and in a second mode to a comparator which produces a digital Caller I.D. output signal. An impedance in the feedback loop of the first and second operational amplifiers is switch-selectable to enable the first and second modes of operation, and each of the selectable reference voltages is chosen to permit proper ring signal detection in a particular corresponding geography.
