Precision, 5V Voltage Reference, Replaced MAX673
General Description
The MAX675 is a precision voltage reference that is
pretrimmed to within ±0.15% of 5V. The reference fea-
tures excellent temperature stability (as low as
12.0ppm/°C guaranteed), low current drain and low
noise. It is supplied in the space-saving narrow SO
package, as well as, the standard 8-pin Plastic DIP
package.

ABSOLUTE MAXIMUM RATINGS
ELECTRICAL CHARACTERISTICS

(VIN= +15V, TA= +25°C, 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.
Note 1:
Temperature Coefficient is measured by the “box” method, i.e., the maximum ΔVOUTis divided by ΔT.
Note 2:
Line and Load Regulation specifications include the effect of self-heating.
Note 3:
Guaranteed by design for MAX675CPA, MAX675CSA, MAX675EPA, MAX675ESA; sample tested for all other grades and
packages.
Note 4:
Limit current in or out of pin 3 to 50nA and capacitance on pin 3 to 30pF.

Output Adjustment

The MAX675 trim terminal can be used to adjust the out-
put voltage over a 5V ±150mV range. This feature allows
system errors to be trimmed by setting the reference to a
voltage other than 5V such as 5.120V for binary applica-
tions (see Typical Operating Circuit). The trim terminal
may, of course, be left open if no adjustment is needed.
Adjustment of the output does not significantly affect the
temperature performance of the device. The temperature
coefficient change is approximately 0.7ppm/°C for each
100mV of output adjustment from its initial value.
Temperature Voltage Output

The MAX675 provides a temperature-dependent output
voltage on the TEMP pin. This voltage is proportional to
the absolute temperature, and has a scale factor of
approximately 2.1mV/°C (Figure 2).
Output Voltage = 2.1(T + 273)mV
