Dolby∗ B Type Noise Reduction System
For the availability of this product, please contact the sales office.
Description
CXA1100, CXA1101, CXA1102 and CXA1163 are
16 pin DIP (Plastic)
16 pin SOP (Plastic)
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)
• Small supply current (—~5.5mA, Typ.)
• 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
