MC1496P Datasheet PDF – Balanced Modulator / Demodulator

Part Number: MC1496P

Function: Balanced Modulator / Demodulator

Package: DIP 14 Pin type

Manufacturer: Motorola (Freescale)


MC1496P datasheet



These devices were 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. See Motorola Application Note AN531 for additional design information.


1. Excellent Carrier Suppression

2. Adjustable Gain and Signal Handling

3. Balanced Inputs and Outputs

4. High Common Mode Rejection – 85 dB typ.
