REF-01/REF-02 Precision Voltage References FEATURES n n n n n n DESCRIPTION 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% with a low 5ppm/°C typical temperature 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 p.

REF-01/REF-02 Precision Voltage References FEATURES n n n n n n DESCRIPTION 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% with a low 5ppm/°C typical temperature 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 temperature. For lower drift and higher accuracy references, please see the LT1019 and LT1021 data sheets. L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
