MC1496, MC1496B Balanced Modulators/ Demodulators 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 ON Semiconductor Application Note AN531 for additional design information. · Excellent Carrier Suppression ­65 dB typ @ 0.5 MHz ­50 dB typ @ 10 MHz · Adjustable Gain and Signal Handling · Balanced Inputs and Outputs · High Common Mode Rejection ­85 dB typical 14 This device contains 8 active transistors. 1 http://onsemi.com SO­14 D SUFFIX CASE 751A 14 1 PDIP­14 P SUFFIX CASE 646 PIN CONNECTIONS Signal Input 1 14 VEE 13 N/C 12 Output 11 N/C 10 Carrier Input 9 N/C 8 Input Carrier Figure 1.
