REF-01/REF-02 Precision Voltage References FEATURES DESCRIPTION n Trimmed Output 0.3% The REF-01/REF-02 are precision 10V and 5V bandgap n Low Drift5ppm/C Typ references which provide stable output voltages over a n Low Noise3ppm wide range of operating conditions. Output voltage is ac- (P-P) n High Line Rejection curate to 0.3% with a low 5ppm/C typical temperature n Temperature OutputREF-02 coef cient. The REF-01 and REF-02 are excellent choices n Low Supply Current 1.4mA Max for applications where low drift, moderate accuracy, low power consumption and low cost are considerations. APPLICATIONS The REF-02 includes a temperature output pin which n A/D and D/A Converters provides a linear voltage proportional to absolute tem- n Precision Regulators perature. n Constant Current Sources n For lower drift and higher accuracy references, please see V/F Converters n the LT1019 and LT1021 data sheets.
