Control Interface
The TLV320DAC3120 control interface supports the I2C communication protocol.
5.8.2.1
I2C Control Mode
The TLV320DAC3120 supports the I2C control protocol, and will respond to the I2C address of 0011 000.
I2C is a two-wire, open-drain interface supporting multiple devices and masters on a single bus. Devices
on the I2C bus only drive the bus lines LOW by connecting them to ground; they never drive the bus lines
HIGH. Instead, the bus wires are pulled HIGH by pullup resistors, so the bus wires are HIGH when no
device is driving them LOW. This way, two devices cannot conflict; if two devices drive the bus
simultaneously, there is no driver contention.
