thin film resistors to achieve 0.05% initial voltage accura- n Less Than 1Ω Dynamic Impedance cy. Improved curvature correction technique guarantees n Both Commercial and Industrial Temperature Range 10ppm/°C maximum temperature drift. Advances in Parts Are Available design, processing and packaging techniques guarantee n Available in 1.25V, 2.5V, 4.096V and 5V in SO-8 10µA operation and low temperature cycling hysteresis. and TO-92 Packages The LT1634 does not require an output compensation n 1.25V and 2.5V Available in MSOP Package capacitor, but is stable with capacitive loads. Low dynamic impedance makes the LT1634 reference easy to use from
