DOUBLE BALANCED MODULATION / DEMODULATOR
■ GENERAL DESCRIPTION The NJM1496 is a double balanced modulator-demodulator which
produces an output voltage proportional to hte 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.
■ FEATURES ● Excellent carrier suppression 65dB typical at 0.5MHz 50dB typical at 10MHz ● Adjustable gain and signal handling ● Fully balanced inputs and outputs ● High Common Mode Rejection 85dB Typ. ● Package Outline DIP14, DMP14, SSOP14 ● Bipolar Technology
■ APPLICATION ● Balanced Modulation ● Synchronous Detection ● FM Detection ● Phase Detection ● Sampling
