MS6282 Datasheet, PDF (7/15 Pages) MOSA ELECTRONICS – Class AB Stereo Headphone Driver, Low voltage Volume Controller

MOSA
MS6282
Volume Controller with soft step IC
BUS INTERFACE
Data are transmitted to and from the MCU to the MS6282 via the SDA and SCL. The SDA and SCL make up the
BUS interface. It should be noted that pull-up resistors must be connected to the positive supply voltage.
Interface protocol
The format consists of the following
•A START condition
•A chip address byte including the MS6282 address. (7bits)
•The 8^th bit of the byte must be “0”.
•The MS6282 must always acknowledge the end of each transmitted byte.
•A data sequence (N-bytes + Acknowledge)
•A STOP condition
Chip Address
The chip address of the MS6282 is 88H.
