Integrated Circuit
Double Balanced Modulator/Demodulator
Description:
The NTE973D is a balanced modulatior/demodulator in a 14–Lead DIP type package designed for
use where the output voltage is a product of an input voltage (signal) and a switching function (carrier).
Typical applications include suppressed carrier and amplitude modulation, synchronous detection,
FM detection, phase detection, and chopper applications.
Features:
D Excellent Carrier Suppression:
65dB typ @ 0.5MHz
50db typ @ 10MHz
D Adjustable Gain and Signal Handling
D Balanced Inputs and Outputs
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
