REF-01/REF-02 Precision Voltage References FEATURES DESCRIPTIO nTrimmed Output –0.3% The REF-01/REF-02 are precision 10V and 5V bandgap nLow Drift—5ppm/°C Typ references which provide stable output voltages over a nLow Noise—3ppm wide range of operating conditions. Output voltage is (P-P) nHigh Line Rejection accurate to –0.3% with a low 5ppm/°C typical temperature nTemperature Output—REF-02 coefficient. The REF-01 and REF-02 are excellent choices nLow Supply Current 1.4mA Max for applications where low drift, moderate accuracy, low U power consumption and low cost are considerations. APPLICATIO S The REF-02 includes a temperature output pin which nA/D and D/A Converters provides a linear voltage proportional to absolute tem- nPrecision Regulators perature. nConstant Current Sources nFor lower drift and higher accuracy references, please see V/F Converters nthe LT1019 and LT1021 data sheets.
