LM1496 Balanced Modulator/Demodulator – Datasheet

The LM1496 is doubled balanced modulator-demodulators which produces an output voltage proportional to the product of an input (signal) voltage and a switching (carrier) signal. Typical applications include suppressed carrier modulation, amplitude modulation, synchronous detection, FM or PM detection, broadband frequency doubling, and chopping. The LM1496 is specified for operation over the 0C to a70C temperature range.
