CXA1100, CXA1101, CXA1102 and CXA1163 are ICs including two separate Dolby B type noise reduction processors. Seven devices with four Dolby levels and two types of package are provided for various applications. These devices feature very few external components, which is achieved by integrated filter circuits using integrated thin film capacitors with high capacitance.
• Minimum number of external components
• NR ON/OFF and REC/PB switchs included
• Small package (DIP16, SOP16)
• Small supply current (—~5.5mA, Typ.)
• Dual channel processors in one chip
