Overview
The MC1496DR2, produced by onsemi, is a balanced modulator/demodulator integrated circuit designed for various modulation and demodulation applications. This device is particularly useful where the output voltage is a product of an input voltage (signal) and a switching function (carrier). It is available in Pb-free packages, making it suitable for modern electronic designs.
