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.

Output Adjustment The REF01 trim terminal can be used to adjust the output voltage over a 10 V ± 300 mV range. This feature lets the system designer trim system errors by setting the reference to a voltage other than 10 V. The output also can be set exactly to 10.000 V or to 10.

REF01 PRECISION CURRENT SOURCE SUPPLY BYPASSING A current source with 25 V output compliance and excellent output impedance can be obtained using this circuit. REF01 keeps the line voltage and power dissipation constant in the device; the only important error consideration at room temperature is the negative supply rejection of the op amp. The typical 3 µV/V PSRR of the OP02E creates an 8 ppm change (3 µV/V × 25 V/10 V) in output current over a 25 V range.
