The ADAM24P20 is remote control transmitter which uses CMOS technology. The ADAM24PXX is suitable for remote control of TV, VCR, FANS, Air-conditioners, Audio Equipments, Toys, Games etc. The ADAM24PXX is MTP version. 1.1.

Remote control transmitters that use CMOS (Complementary Metal-Oxide-Semiconductor) technology are quite common due to the advantages of CMOS in terms of power efficiency, low static power consumption, and ease of integration with other circuitry. CMOS technology allows for the development of compact and energy-efficient remote control devices.

CMOS technology allows for the integration of various functions on a single chip, reducing component count and power consumption. It is commonly used in remote control transmitters found in various consumer electronics like TVs, set-top boxes, DVD players, and other remote-controlled devices. The efficient power management of CMOS technology also helps extend battery life in battery-operated remote controls.
