1 +1V Precision VOLTAGE REFEREE FEATURES OUTPUT VOLTAGE: +1V ±.% max EXCELLENT TEMPERATURE STABILITY: 8.ppm/ C max ( C to +8 C) LOW NOISE: µvp-p typ (.1Hz to 1Hz) EXCELLENT LINE REGULATION:.1%/V max EXCELLENT LOAD REGULATION:.%/mA max SOURCES 1mA, SINKS ma min LOW SUPPLY CURRENT: 1.mA max SHORT-CIRCUIT PROTECTED WIDE SUPPLY RANGE: 11.VDC to VDC PACKAGE OPTIONS: Plastic DIP, SOIC EXTENDED INDUSTRIAL TEMPERATURE RANGE: C to +8 C DESCRIPTION The is a high performance, low price, precision pin compatible second source voltage reference. Output accuracy of ±.% is a 3% improvement over industry standard s. Output noise is µvp-p, which is a 7% decrease in noise over all other s. Line regulation is.1%/v max and load regulation is.%/ma max, which far exceeds the performance of our competitors. Quiescent current is a low 1.mA. provides extended supply range when compared to industry standard devices. Burr- Brown s is the best choice for applications which requires improved accuracy, low noise, low power consumption, low drift, and the lowest price. Popular package options are available: Plastic DIP, and SOIC. For guaranteed long-term drift see Burr- Brown s model REF1.

6 OUTPUT ADJUSTMENT The trim terminal can be used to adjust the voltage over a 1V ±3mV range. This feature allows the system designer to trim system errors by setting the reference to a voltage other than 1V, including 1.V for binary applications (see circuit on the first page). Adjustment of the output does not significantly affect the temperature performance of the device. The temperature coefficient change is approximately.ppm/ C for 1mV of output adjustment.
