FEATURES 10 V output, ±0.3% maximum Adjustment range, ±3% minimum Excellent temperature stability, 8.5 ppm/°C maximum Low noise, 30 µV p-p maximum Low supply current, 1.4 mA maximum Wide input voltage range, 12 V to 40 V High load driving capability, 10 mA No external components Short-circuit proof GENERAL DESCRIPTION The REF01 precision voltage reference provides a stable 10 V output that can be adjusted over a 3% range with minimal effect on temperature stability. Single-supply operation over an input voltage range of 12 V to 40 V, a low current drain of 1 mA, and excellent temperature stability are achieved with an improved band gap design. Low cost, low noise, and low power make the REF01 an excellent choice whenever a stable voltage reference is required. Applications include DACs and ADCs, portable instrumentation, and digital voltmeters. Full military temperature range devices with screening to MIL-STD-883 are available. For new designs, refer to ADR01. PIN CONFIGURATIONS 1 2 3 4 5 6 7 8 NC GROUND (CASE) NC VIN VOUT NC NC TRIM NC = NO CONNECT. DO NOT CONNECT ANYTHING ON THESE PINS.
