CXA1553P

Manufacturer Part Number
CXA1553P
Description
Dolby B type Noise Reduction System
Manufacturer
Sony
Datasheet
Description
bipolar ICs providing two separate Dolby B type
noise reduction processors.
composed of seven devices having four Dolby levels
and two types of package for various applications.
These devices feature very few external
components, which is achieved by monolithic filter
circuits using integrated thin film capacitors with high
capacitance.
Features
• Pin replaceable with CXA1100 series
• Minimum number of external components
• NR ON/OFF/Double Speed, REC/PB switches
• Small package (16 pin SOP, 16 pin DIP)
• Low current consumption 5.6mA typ.
• Dual channel processors in one chip
• Double speed encode and decode functions are
The CXA1550/CXA1551/CXA1552/CXA1553 are
included
