I2C Serial Interface
The MAX5961 features an I2C-compatible serial interface
consisting of a serial-data line (SDA) and a serial-clock
line (SCL). SDA and SCL allow bidirectional communica-
tion between the MAX5961 and the master device at
clock rates from 100kHz to 400kHz. The I2C bus can
have several devices (e.g., more than one MAX5961, or
other I2C devices in addition to the MAX5961) attached
simultaneously. The A0 and A1 inputs set one of nine
possible I2C addresses (see Table 51).
The 2-wire communication is fully compatible with exist-
ing 2-wire serial-interface systems; Figure 5 shows the
interface timing diagram. The MAX5961 is a
transmit/receive slave-only device, relying upon a mas-
ter device to generate a clock signal. The master
device (typically a C) initiates data transfer on the bus
and generates SCL to permit that transfer.
A master device communicates to the MAX5961 by
transmitting the proper address followed by command
and/or data words. Each transmit sequence is framed
by a START (S) or REPEATED START (SR) condition
and a STOP (P) condition. Each word transmitted over
the bus is 8 bits long and is always followed by an
acknowledge pulse.
SCL is a logic input, while SDA is a logic-input/open-
drain output. SCL and SDA both require external pullup
resistors to generate the logic-high voltage. Use 4.7kΩ
for most applications.
