General Description
The MAX5512–MAX5515 are dual, 8-bit, ultra-low-
power, voltage-output, digital-to-analog converters
(DACs) offering Rail-to-Rail®buffered voltage outputs.
The DACs operate from a 1.8V to 5.5V supply and con-
sume less than 5µA, making the devices suitable for
low-power and low-voltage applications. A shutdown
mode reduces overall current, including the reference
input current, to just 0.18µA. The MAX5512–MAX5515
use a 3-wire serial interface that is compatible with
SPI™, QSPI™, and MICROWIRE™.
Upon power-up, the MAX5512–MAX5515 outputs are
driven to zero scale, providing additional safety for
applications that drive valves or for other transducers
that need to be off during power-up. The zero-scale
outputs enable glitch-free power-up.
The MAX5512 accepts an external reference input and
provides unity-gain outputs. The MAX5513 contains a
precision internal reference and provides a buffered
external reference output with unity-gain DAC outputs.
The MAX5514 accepts an external reference input and
provides force-sense outputs. The MAX5515 contains a
precision internal reference and provides a buffered
external reference output with force-sense DAC outputs.
The MAX5514/MAX5515 are available in a 4mm x 4mm
x 0.8mm, 12-pin, thin QFN package. The MAX5512/
MAX5513 are available in an 8-pin µMAX package. All
devices are guaranteed over the extended -40°C to
+85°C temperature range.
For 10-bit compatible devices, refer to the MAX5522–
MAX5525 data sheet. For 12-bit compatible devices,
refer to the MAX5532–MAX5535 data sheet.

Detailed Description
The MAX5512–MAX5515 dual, 8-bit, ultra-low-power,
voltage-output DACs offer Rail-to-Rail buffered voltage
outputs. The DACs operate from a 1.8V to 5.5V supply
and require only 5µA (max) supply current. These
devices feature a shutdown mode that reduces overall
current, including the reference input current, to just
0.18µA (max). The MAX5513/MAX5515 include an inter-
nal reference that saves additional board space and can
source up to 8mA, making it functional as a system refer-
ence. The 16MHz, 3-wire serial interface is compatible
with SPI, QSPI, and MICROWIRE protocols. When VDD is
applied, all DAC outputs are driven to zero scale with vir-
tually no output glitch. The MAX5512/MAX5513 output
buffers are configured in unity gain and come in µMAX
packages. The MAX5514/MAX5515 output buffers are
configured in force sense allowing users to externally set
voltage gains on the output (an output-amplifier inverting
input is available). The MAX5514/MAX5515 come in
4mm x 4mm thin QFN packages.
Digital Interface
The MAX5512–MAX5515 use a 3-wire serial interface
that is compatible with SPI/QSPI/MICROWIRE protocols
(Figures 1 and 2).
The MAX5512–MAX5515 include a single, 16-bit, input
shift register. Data loads into the shift register through
the serial interface. CS must remain low until all 16 bits
are clocked in. The 16 bits consist of 4 control bits
(C3–C0), 8 data bits (D7–D0) (Table 1), and 4 sub-bits
(S3–S0). The sub-bits must be set to zero for proper
operation. Following the 4 control bits, the data loads
MSB first, D7–D0. D7–D0 are the DAC data bits and
S3–S0 are the sub-bits. The control bits C3–C0 control
the MAX5512–MAX5515, as outlined in Table 2.
Each DAC channel includes two registers: an input reg-
ister and a DAC register. The input register holds input
data. The DAC register contains the data updated to
the DAC output.
The double-buffered register configuration allows any
of the following:
•Loading the input registers without updating the DAC
registers
•Updating the DAC registers from the input registers
•Updating all the input and DAC registers simultaneously

X = Don’t care.
*Standby mode can be entered from normal operation only. It is not possible to enter standby mode from shutdown.
Power Modes
The MAX5512–MAX5515 feature two power modes to
conserve power during idle periods. In normal opera-
tion, the device is fully operational. In shutdown mode,
the device is completely powered down, including the
internal voltage reference in the MAX5513/MAX5515.
The MAX5513/MAX5515 also offer a standby mode in
which all circuitry is powered down except the internal
voltage reference. Standby mode keeps the reference
powered up while the remaining circuitry is shut down,
allowing it to be used as a system reference. It also
helps reduce the wake-up delay by not requiring the ref-
erence to power up when returning to normal operation.
Shutdown Mode
The MAX5512–MAX5515 feature a software-programma-
ble shutdown mode that reduces the supply current and
the reference input current to 0.18µA (max). Writing an
input control word with control bits C[3:0] = 1110 (Table
2) places the device in shutdown mode. In shutdown,
the MAX5512/MAX5514 reference input and DAC output
buffers go high impedance. Placing the MAX5513/
MAX5515 into shutdown turns off the internal reference
and the DAC output buffers go high impedance. The ser-
ial interface still remains active for all devices.
Table 2 shows several commands that bring the
MAX5512–MAX5515 back to normal operation. The
power-up time from shutdown is required before the
DAC outputs are valid.
Note: For the MAX5513/MAX5515, standby mode can-
not be entered directly from shutdown mode. The
device must be brought into normal operation first
before entering standby mode.
Standby Mode (MAX5513/MAX5515 Only)
The MAX5513/MAX5515 feature a software-program-
mable standby mode that reduces the typical supply
current to 3µA (max). Standby mode powers down all
circuitry except the internal voltage reference. Place
the device in standby mode by writing an input control
word with control bits C[3:0] = 1100 (Table 2). The
internal reference and serial interface remain active
while the DAC output buffers go high impedance.
For the MAX5513/MAX5515, standby mode cannot be
entered directly from shutdown mode. The device must
be brought into normal operation first before entering
standby mode. To enter standby from shutdown, issue
the command to return to normal operation followed
immediately by the command to go into standby.
Table 2 shows several commands that bring the
MAX5513/MAX5515 back to normal operation. When
transitioning from standby mode to normal operation,
only the DAC power-up time is required before the DAC
outputs are valid.
Reference Input
The MAX5512/MAX5514 accept a reference with a volt-
age range extending from 0 to VDD. The output voltage
(VOUT) is represented by a digitally programmable volt-
age source as:
VOUT = (VREF x N / 256) x gain
where N is the numeric value of the DAC’s binary input
code (0 to 255), VREF is the reference voltage, gain is the
externally set voltage gain for the MAX5514, and gain is
one for the MAX5512.
In shutdown mode, the reference input enters a high-
impedance state with an input impedance of 2.5GΩ(typ).
Reference Output
The MAX5513/MAX5515 internal voltage reference is
software configurable to one of four voltages. Upon
power-up, the default reference voltage is 1.214V.
Configure the reference voltage using D7 and D6 data
bits (Table 3) when the control bits are as follows C[3:0]
= 1100, 1101, or 1110 (Table 2). VDD must be kept at a
minimum of 200mV above VREF for proper operation.

Applications Information
1-Cell and 2-Cell Circuits
See Figure 3 for an illustration of how to power the
MAX5512–MAX5515 with either one lithium-ion battery
or two alkaline batteries. The low current consumption
of the devices make the MAX5512–MAX5515 ideal for
battery-powered applications.
Programmable Current Source
See the circuit in Figure 4 for an illustration of how to
configure the MAX5514/MAX5515 as a programmable
current source for driving an LED. The MAX5514/
MAX5515 drive a standard NPN transistor to program
the current source. The current source (ILED) is defined

Voltage Biasing a

See the circuit in Figure 5 for an illustration of how to
configure the MAX5514/MAX5515 to bias a current-out-
put transducer. In Figure 5, the output voltage of the
MAX5514/MAX5515 is a function of the voltage drop
across the transducer added to the voltage drop
across the feedback resistor R.
Unipolar Output
Figure 6 shows the MAX5514 in a unipolar output con-
figuration with unity gain. Table 4 lists the unipolar out-
put codes.
Bipolar Output
The MAX5514 output can be configured for bipolar
operation as shown in Figure 7. The output voltage is
given by the following equation:
VOUT_ = VREFIN x [(NA- 128) / 128]
where NArepresents the decimal value of the DAC’s
binary input code. Table 5 shows the digital codes (off-
set binary) and the corresponding output voltage for
the circuit in Figure 7.
Configurable Output Gain
The MAX5514/MAX5515 have force-sense outputs,
which provide a connection directly to the inverting ter-
minal of the output op amp, yielding the most flexibility.
The advantage of the force-sense output is that specific
gains can be set externally for a given application. The
gain error for the MAX5514/MAX5515 is specified in a
unity-gain configuration (op-amp output and inverting
terminals connected), and additional gain error results
from external resistor tolerances. Another advantage of
the force-sense DAC is that it allows many useful circuits
to be created with only a few simple external components.
An example of a custom fixed gain using the MAX5514/
MAX5515 force-sense output is shown in Figure 9. In
this example, R1 and R2 set the gain for VOUTA.
VOUTA = [(VREFIN x NA) / 256] x [1 + (R2 / R1)]
where NArepresents the numeric value of the DAC
input code.

Power Supply and
Bypassing Considerations
Bypass the power supply with a 0.1µF capacitor to GND.
Minimize lengths to reduce lead inductance. If noise
becomes an issue, use shielding and/or ferrite beads to
increase isolation. For the thin QFN package, connect the
exposed pad to ground.
Layout Considerations
Digital and AC transient signals coupling to GND can
create noise at the output. Use proper grounding tech-
niques, such as a multilayer board with a low-inductance
ground plane. Wire-wrapped boards and sockets are not
recommended. For optimum system performance, use
printed circuit (PC) boards. Good PC board ground lay-
out minimizes crosstalk between DAC outputs, reference
inputs, and digital inputs. Reduce crosstalk by keeping
analog lines away from digital lines.
