Lm1496n Lm1496 Modulador-demodulador Equilibrado

Descripción

The LM1596 LM1496 are doubled balanced modulator-demodulators which produce 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 or PM detection broadband frequency doubling and chopping The LM1596 is specified for operation over the 125 C military temperature range The LM1496 is specified for operation over the 70 C temperature range

Features
Excellent carrier suppression 65 dB typical 0 5 MHz 50 dB typical at 10 MHz Adjustable gain and signal handling Fully balanced inputs and outputs Low offset and drift Wide frequency response to 100 MHz

Note Pin 10 is connected electrically to the case through the device substrate
