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.

+5V Precision Voltage Reference MAX675 Output Adjustment The MAX675 trim terminal can be used to adjust the output 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 applications (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.
