AN2020S
Dual Balanced Modulator IC
s Overview
The AN2020S is an integrated circuit which incor-
porates two balanced modulators.
It can be used for a video-frequency-band dual am-
plifier, variable gain amplifier, balanced modulator,
demodulator, etc.
s Features
• Low voltage operation:4.8V(typ.)
• Carrier suppression:–43dB(typ.)
• Dual balanced modulator
• Superimpose of DC offset to input signal available
• External adjustment of high level limitation to input
