Integrated Circuit
Double Balanced Modulator/Demodulator
14-PIN DIP
Info als pdf-File
Description:
The NTE973D is a balanced modulator/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 dtetction, FM detection, phase detection, and chopper applications.
Features:
- Excellent Carrier Suppresion:
56dB Typ @ 0.5MHz
50dB Typ @ 10MHz - Adjustable Gain and Signal Handling
- Balanced Inputs and Outputs
Absolute Maximum Ratings: (T
A = +25°C unless otherwise specified)
