Maxim REF01AJ, REF01AZ, REF01CJ, REF01CP, REF01HZ Datasheet

19-0887; Rev 1; 8/99

General Description

The REF01 and REF02 are precision voltage references that are pretrimmed to within ±3% of +10V and +5V, respectively. Both references feature excellent temperature stability (as low as 8.5 ppm/°C worst case), low current drain, and low noise. The REF02 also provides a TEMP pin whose output voltage varies linearly with temperature, making this device suitable for a wide variety of temperature-sensing and control applications. Both devices are available from Maxim in the space-saving SO package, as well as in the standard 8-pin TO-99 and MINI-DIP packages.

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.

Output Adjustment

The REF01 trim terminal can be used to adjust the voltage over a 10V±300mV range. This feature allows the system designer to trim system errors by setting the reference to a voltage other than 10V, including 10.240V for binary applications (see the Typical Operating Circuit section).

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.
