Overview
The MC1496BDR2G is a balanced modulator/demodulator integrated circuit produced by onsemi. This device is designed for applications where the output voltage is the product of an input voltage (signal) and a switching function (carrier). It is particularly useful in suppressed carrier and amplitude modulation, synchronous detection, FM detection, phase detection, and chopper applications.
