+5V, Serial-Input, Voltage-Output, 14-Bit DACs
General DescriptionThe MAX544/MAX545 are serial-input, voltage-output,
14-bit digital-to-analog converters (DACs) that operate
from a single +5V supply. They provide 14-bit perfor-
mance (±0.5LSB INL and ±0.9LSB DNL) over tempera-
ture without any adjustments. The DAC output is
unbuffered, resulting in a low supply current of 0.3mA
and a low offset error of 0.6mV.
The DAC output range is 0V to VREF.For bipolar opera-
tion, matched scaling resistors are provided in the
MAX545 for use with an external precision op amp
(such as the MAX400), generating a ±VREFoutput
swing. The MAX545 also includes Kelvin-sense con-
nections for the reference and analog ground pins to
reduce layout sensitivity.
A 16-bit serial word is used to load data into the DAC
latch. The 10MHz, 3-wire serial interface is compatible
with SPI™/QSPI™/MICROWIRE™, and it also interfaces
directly with optocouplers for applications requiring isola-
tion. A power-on reset circuit clears the DAC output to 0V
(unipolar mode) when power is initially applied.
The MAX544 is available in 8-pin plastic DIP and SO
packages. The MAX545 is available in 14-pin plastic
DIP and SO packages.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS(VDD= +5V ±5%, VREF= +2.5V, AGND = DGND = 0, TA= TMINto TMAX, unless otherwise noted.)
Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.

TIMING CHARACTERISTICS(VDD= +5V ±5%, VREF= +2.5V, AGND = DGND = 0, CMOS inputs, TA= TMINto TMAX, unless otherwise noted.)
Note 1:Gain Error tested at VREF= 2.0V, 2.5V, and 3.0V.
Note 2:ROUTtolerance is typically ±20%.
Note 3:Min/max range guaranteed by gain-error test. Operation outside min/max limits will result in degraded performance.
Note 4:Reference input resistance is code dependent, minimum at 8554 hex.
Note 5:Slew-rate value is measured from 0% to 63%.
Note 6:Guaranteed by design. Not production tested.
