CXA1100P, CXA1101P/M, CXA1102P/M, CXA1163P/M Dolby∗ B Type Noise Reduction System For the availability of this product, please contact the sales office. Description 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. Features • Minimum number of external components • NR ON/OFF and REC/PB switchs included • Small package (DIP16, SOP16) ~ 5.5mA, Typ.) • Small supply current (— • Dual channel processors in one chip Absolute Maximum Ratings (Ta = 25°C) • Supply voltage VCC 17 V • Operating temperature Topr –30 to +85 °C • Storage temperature Tstg –55 to +150 °C • Allowable power dissipation PD DIP16 (A1100P/A1101P/A1102P/A1163P)900 mW SOP16 (A1101M/A1102M/A1163M) 500 mW Note 1) These ICs are available only to the licensees of Dolby Laboratories Licensing Corporation from whom licensing and application information may be obtaind.
