IF R6 = R3, BRIDGE IS NOT LOADED BY R2 AND R4. A1 VOS AND DRIFT ARE NOT CRITICAL. * ** † TA01a –5V APPLICATIO S DESCRIPTIO FEATURES TYPICAL APPLICATIO ■ A/D and D/A Converters ■ Precision Regulators ■ Constant Current Sources ■ V/F Converters ■ Bridge Excitation ■ Trimmed Output ±0.3% ■ Low Drift—5ppm/ °C Typ ■ Low Noise—3ppm(P-P) ■ High Line Rejection ■ Temperature Output—REF-02 ■ Low Supply Current 1.4mA Max Precision Voltage References The REF-01/REF-02 are precision 10V and 5V bandgap references which provide stable output voltages over a wide range of operating conditions. Output voltage is accurate to ±0.3%withalow5ppm/°Ctypicaltemperature coefficient. The REF-01 and REF-02 are excellent choices for applications where low drift, moderate accuracy, low power consumption and low cost are considerations. The REF-02 includes a temperature output pin which provides a linear voltage proportional to absolute tem- perature. For lower drift and higher accuracy references, please see the LT1019 and LT1021 data sheets. , LTC and LT are registered trademarks of Linear Technology Corporation.
