LM1596LM1496 Balanced Modulator-Demodulator

General Description

The LM1596LM1496 are doubled balanced modulator-de-

modulators which produce an output voltage proportional to

the product of an input (signal) voltage and a switching (car-

rier) signal Typical applications include suppressed carrier

modulation amplitude modulation synchronous detection

FM or PM detection broadband frequency doubling and

chopping
