The MK484 AM radio IC is a fully functional AM radio detector on a chip. It is constructed in a TO-92 case, resembling a small transistor. It replaces the similar ZN414 AM radio IC from the 1970s. The MK484 is favored by many hobbyists. It is advantageous in that it performs well with minimal discrete components, and can run from a single 1.5-volt cell.〔 Rapid Electronics Ltd., ("MK484 Radio IC" datasheet ) 〕〔 http://www.vk6fh.com/vk6fh/mk484radios.htm 〕 ==Standard operation== The simplest circuit employing the MK484 can be constructed using only a battery, an earphone (or high-impedance speaker), a coil and a variable capacitor. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「MK484」の詳細全文を読む スポンサード リンク
