+5V, Serial-Input, Voltage-Output, 16-Bit DACs
General Description
The MAX541/MAX542 are serial-input, voltage-output,
16-bit digital-to-analog converters (DACs) that operate
from a single +5V supply. They provide 16-bit perfor-
mance (±1LSB INL and DNL) over temperature without
any adjustments. The DAC output is unbuffered, result-
ing in a low supply current of 0.3mA and a low offset
error of 1LSB.
The DAC output range is 0V to VREF. For bipolar opera-
tion, matched scaling resistors are provided in the
MAX542 for use with an external precision op amp
(such as the MAX400), generating a ±VREFoutput
swing. The MAX542 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 MAX541 is available in 8-pin plastic DIP and SO
packages. The MAX542 is available in 14-pin plastic
DIP and SO packages.

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 8555 hex.
Note 5:
Slew-rate value is measured from 0% to 63%.
Note 6:
Guaranteed by design. Not production tested.
