DESCRIPTION
The LT®1634 is a micropower, precision, shunt voltage
reference. The bandgap reference uses trimmed precision
thin film resistors to achieve 0.05% initial voltage accu-
racy. Improved curvature correction technique guaran-
tees 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.
