FEATURES
s s s s s DESCRIPTIO Initial Voltage Accuracy: 0.05% Low Operating Current: 800nA Low Drift: 10ppm/°C Max Less Than 1Ω Dynamic Impedance Available in 1.25V, 2.5V, 4.096V and 5V SO-8 Packages U APPLICATIO S s s s s The LT ®1389 is a nanopower, precision shunt voltage reference. The bandgap reference uses trimmed precision thin-film resistors and improved curvature correction techniques to achieve 0.05% initial voltage accuracy with guaranteed 10ppm/°C maximum temperature drift. Voltage regulation is maintained to an ultralow 800nA operating current. Advances in design, processing and packaging achieve low temperature cycling hysteresis. , LTC and LT are registered trademarks of Linear Technology Corporation.
