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.

+10V Precision Voltage Reference 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 reference 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. Typical Operating Characteristics (TA = +25°C, unless otherwise noted.) MAX674 OUTPUT WIDEBAND NOISE vs. BANDWIDTH (0.
