+10V Precision Voltage Reference
General Description
The MAX674 is a precision voltage reference that is
pretrimmed to within ±0.15% of 10V. 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.
Features
♦ Pretrimmed to +10V, ±0.15%
♦ Excellent Temperature Stability: 12ppm/°C
♦ Low Noise: 20µVP-P
♦ Low Supply Current: 1.4mA (max)
♦ Short-Circuit Protected
♦ Load Regulation 0.001%/mA
♦ Pin-for-Pin Compatible with REF01

Output Adjustment
The MAX674 trim terminal can be used to adjust the
output voltage over a 10V ±300mV range. This feature
allows system errors to be trimmed by setting the refer-
ence to a voltage other than 10V such as 10.240V for
binary applications (see the 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
100mV of output adjustment from its initial value.
(TA = +25°C, unless otherwise noted.)
