Balanced modulator/demodulator
DESCRIPTION
MC1496/MC1596
FEATURES
The MC1496 is a monolithic double-balanced modulator/demodulator designed for use where the output voltage is a product of an input voltage (signal) and a switched function (carrier). The MC1596 will operate over the full military temperature range of -55 to +125°C. The MC1496 is intended for applications within the range of 0 to +70°C.
PIN CONFIGURATION
• Excellent carrier suppression
