Description
stereo Dolby B-C type noise reduction (NR) system.
combination of three line output levels and two
packages for various applications.
small package have been achieved due to the fact
that the spectral skewing circuits are all on-chip.
Features
• Few external parts
• Spectral skewing circuit are on-chip
• NR ON/OFF, REC/PB, MPX filter ON/OFF switches
• Small package (24-pin SOP, 22-pin SDIP)
• Low current consumption 13mA Typ.
Structure
Absolute Maximum Ratings (Ta = 25°C)
• Supply voltage
• Operating temperature
• Storage temperature
• Allowable power dissipation
The CXA1560 series is a bipolar IC incorporating
Five kinds of device are provided due to the
A reduction in the number of external parts and
(power supply ±6V)
Bipolar silicon monolithic IC
