® REF01 +10V Precision VOLTAGE REFERENCE FEATURES DESCRIPTION ● OUTPUT VOLTAGE: +10V ±0.2% max ● EXCELLENT TEMPERATURE STABILITY: 8.5ppm/°C max (–40°C to +85°C) ● LOW NOISE: 5µVp-p typ (0.1Hz to 10Hz) ● EXCELLENT LINE REGULATION: 0.001%/V max ● EXCELLENT LOAD REGULATION: 0.002%/mA max ● SOURCES 10mA, SINKS 5mA min ● LOW SUPPLY CURRENT: 1.4mA max ● SHORT-CIRCUIT PROTECTED ● WIDE SUPPLY RANGE: 11.4VDC to 40VDC ● PACKAGE OPTIONS: Plastic DIP, SOIC The REF01 is a high performance, low price, precision pin compatible second source voltage reference. Output accuracy of ±0.2% is a 30% improvement over industry standard REF01s. Output noise is 5µVp-p, which is a 75% decrease in noise over all other REF01s. Line regulation is 0.001%/V max and load regulation is 0.002%/mA max, which far exceeds the performance of our competitors. Quiescent current is a low 1.4mA. REF01 provides extended supply range when compared to industry standard devices. BurrBrown’s REF01 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 BurrBrown’s model REF10. ● EXTENDED INDUSTRIAL TEMPERATURE RANGE: –40°C to +85°C APPLICATIONS ● ● ● ● ● ● 2 PRECISION REGULATORS CONSTANT CURRENT SOURCE/SINK DIGITAL VOLTMETERS A/D AND D/A CONVERTERS PRECISION CALIBRATION STANDARD TEST EQUIPMENT VIN VOUT 6 Output REF01 Trim GND 5 RPOT 10kΩ (Optional) 4 +10V Reference with Trimmed Output International Airport Industrial Park • Mailing Address: PO Box 11400, Tucson, AZ 85734 • Street Address: 6730 S.
