Leiterrahmen-Kondensator

摘要

A capacitor (10) is provided including first and second electrodes (12,14) formed from portions of the lead frame structure (30) used in conventional integrated circuit packaging. The electrodes (12,14) are encapsulated with dielectric molding material (40) which provides dielectric insulation between the electrodes (12,14). A low power capacitively-coupled digital isolator circuit (50) is also provided. The circuit employs a pair of the lead frame capacitors (105,115) of the present invention and includes differential driver and receiver circuits (110,120). The receiver (120) can also include an optional filter (136) for increasing noise and glitch immunity.
