Micropower Precision

Shunt Voltage Reference

FeaTures

DescripTion

The

1634

is a micropower, precision, shunt voltage

reference. The bandgap reference uses trimmed precision

thin film resistors to achieve 0.05% initial voltage accura-

cy. 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.
