Overview

Initial Voltage Accuracy: 0.05%
Low Operating Current: 10μA
Low Drift: 10ppm/°C Max
Less Than 1Ω Dynamic Impedance
Both Commercial and Industrial Temperature Range Parts Are Available
Available in 1.25V, 2.5V, 4.096V and 5V in SO-8 and TO-92 Packages
1.25V and 2.5V Available in MSOP Package

The LT1634 is a micropower, precision, shunt voltage reference. The bandgap reference uses trimmed precision thin film resistors to achieve 0.05% initial voltage accuracy.Improved curvature correction technique guarantees 10ppm/°C maximum temperature drift. Advances in design, processing and packaging techniques guarantee 10µA operation and low temperature cycling hysteresis.The LT1634 does not require an output compensation capacitor, but is stable with capacitive loads. Low dynamic impedance makes the LT1634 reference easy to use from unregulated supplies.

The LT1634 reference can be used as a high performance upgrade to the LM185/LM385, LT1004 and LT1034 where lower power and guaranteed temperature drift is required.

Applications

Portable Meters
Precision Regulators
A/D and D/A Converters
