I2C Bus Sound Processor for TV
CXA2022S
Description
The CXA2022S is a bipolar IC designed as an I2C
bus control sound processor for TV. This IC has
simulate stereo, surround, tone control, balance,
volume, muting, AGC and other functions.
30 pin SDIP (Plastic)
Features
• Allows control by I2C bus
• Employs a special surround system to prevent
"vocal missing" in the surround mode
• Adopts an AGC circuit to absorb the difference in
sound level between input sources and improves
S/N ratio of hearing characteristics
Absolute Maximum Ratings
• Supply voltage
VCC 14 V
• Operating temperature
Topr –20 to +75 °C
• Storage temperature
Tstg –65 to +150 °C
• Allowable power dissipation PD
1.25 W
