BA8272AFV
BA8272AFV is a BUS interface IC (slave side) developed for car audio systems. Communication system of BUS ON,
DATA, CLOCK, and RESET can be constructed in combination with BA8270F / BA8270FV (master side). This IC can be
used for communication between the audio system and other applications such as power amplifier, CD, MD changer,
navigation and TV.
!Applications
Car audio
!Features
1) It can be used for 3V Interface system.
2) It can build up the communication system of BUS ON, DATA, CLOCK and RESET in combination with BA8270FV
(IC at a master side) in pairs.
3) Suitable for car audio.
