| ML12002 Analog Mixer Legacy Device: Motorola MC12002 The ML12002 is a double balanced analog mixer, including an input amplifier feeding the mixer carrier port and a temperature compensated bias regulator. The input circuits for both the amplifier and mixer are differential amplifier circuits. The on-chip regulator provides all of the required biasing. This circuit is designed for use as a balanced mixer in high-frequency wide-band circuits. Other typical applications include suppressed carrier and amplitude modulation, synchronous AM detection, FM detection, phase detection, and frequency doubling, at frequencies up to UHF. There are two package offerings: * Plastic Dual Inline 14 Lead, P Dip. * Plastic Surface Mount 14 Lead SOIC. * Operating Temperature Range: TA = -30 to +85C 14 1 P DIP 14 = CP PLASTIC PACKAGE CASE 646 SOG 14 = -5P SOG CASE 751A CROSS REFERENCE/ORDERING INFORMATION MOTOROLA LANSDALE PACKAGE P DIP 14 MC12002P ML12002CP SOG 14 MC12002D ML12002-5P Note: Lansdale lead free (Pb) product, as it becomes available, will be identified by a part number prefix change from ML to MLE.
