2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs
_______________General Description
The MAX517/MAX518/MAX519 are 8-bit voltage output
digital-to-analog converters (DACs) with a simple 2-wire
serial interface that allows communication between
multiple devices. They operate from a single 5V supply
and their internal precision buffers allow the DAC out-
puts to swing rail-to-rail.
The MAX517 is a single DAC and the MAX518/MAX519
are dual DACs. The MAX518 uses the supply voltage
as the reference for both DACs. The MAX517 has a ref-
erence input for its single DAC and each of the
MAX519’s two DACs has its own reference input.
The MAX517/MAX518/MAX519 feature a serial interface
and internal software protocol, allowing communication
at data rates up to 400kbps. The interface, combined
with the double-buffered input configuration, allows the
DAC registers of the dual devices to be updated indi-
vidually or simultaneously. In addition, the devices can
be put into a low-power shutdown mode that reduces
supply current to 4µA. Power-on reset ensures the DAC
outputs are at 0V when power is initially applied.
The MAX517/MAX518 are available in space-saving 8-
pin DIP and SO packages. The MAX519 comes in 16-
pin DIP and SO packages.

Note 1:
For the MAX518 (full-scale = VDD) the last three codes are excluded from the TUE and DNL specifications, due to the limited
output swing when loaded with 10kΩto GND.

Input resistance is code dependent. The lowest input resistance occurs at code = 55 hex.
Note 3:
Input capacitance is code dependent. The highest input capacitance occurs at code FF hex.
Note 4:
VREF_= 4Vp-p, 10kHz. Channel-to-channel isolation is measured by setting the code of one DAC to FF hex and setting the
code of all other DACs to 00 hex.

Note 9:
A master device must provide a hold time of at least 300ns for the SDA signal (referred to VILof the SCL signal) in order to

_______________Detailed Description
Serial Interface

The MAX517/MAX518/MAX519 use a simple 2-wire
serial interface requiring only two I/O lines (2-wire bus)
of a standard microprocessor (µP) port. Figure 2 shows
the timing diagram for signals on the 2-wire bus.
Figure 3 shows a typical application. The 2-wire bus can
have several devices (in addition to the MAX517/
MAX518/MAX519) attached. The two bus lines (SDA and
SCL) must be high when the bus is not in use. When in
use, the port bits are toggled to generate the appropriate
signals for SDA and SCL. External pull-up resistors are
not required on these lines. The MAX517/MAX518/
MAX519 can be used in applications where pull-up resis-
tors are required (such as in I2C systems) to maintain
compatibility with existing circuitry.
The MAX517/MAX518/MAX519 are receive-only devices
and must be controlled by a bus master device. They
operate at SCL rates up to 400kHz. Amaster device
sends information to the devices by transmitting their
address over the bus and then transmitting the desired
information. Each transmission consists of a START
condition, the MAX517/MAX518/MAX519’s programm-
able slave-address, one or more command-byte/out-
put-byte pairs (or a command byte alone, if it is the last
byte in the transmission), and finally, a STOP condition
(Figure 4).
MAX517/MAX518/MAX519
2-Wire Serial 8-Bit DACs with
Rail-to-Rail Outputs_______________________________________________________________________________________

The address byte and pairs of command and output
bytes are transmitted between the STARTand STOPcon-
ditions. The SDA state is allowed to change only while
SCL is low, with the exception of STARTand STOPcondi-
tions. SDA’s state is sampled, and therefore must remain
stable while SCL is high. Data is transmitted in 8-bit
bytes. Nine clock cycles are required to transfer the data
bits to the MAX517/MAX518/MAX519. Set SDA low dur-
ing the 9th clock cycle as the MAX517/MAX518/MAX519
pull SDA low during this time. RC(see Figure 3) limits the
current that flows during this time if SDA stays high for
short periods of time.
The START and STOP Conditions

When the bus is not in use, both SCL and SDA must be
high. A bus master signals the beginning of a transmis-
sion with a START condition by transitioning SDA from
high to low while SCL is high (Figure 5). When the mas-
ter has finished communicating with the slave, it issues
a STOP condition by transitioning SDA from low to high
while SCL is high. The bus is then free for another
transmission.
The Slave Address

The MAX517/MAX518/MAX519 each have a 7-bit long
slave address (Figure 6). The first three bits (MSBs) of
the slave address have been factory programmed and
are always 010. In addition, the MAX517 and MAX518
have the next two bits factory programmed to 1s. The
logic state of the address inputs (AD0 and AD1 on the
MAX517/MAX518; AD0, AD1, AD2, and AD3 on the
MAX519) determine the LSB bits of the 7-bit slave
address. These input pins may be connected to VDD or
DGND, or they may be actively driven by TTL or CMOS
logic levels. The MAX517/MAX518 have four possible
slave addresses and therefore a maximum of four of
