DESCRIPTION
This monolithic integrated circuit is a fully self-contained precision voltage
reference generator, internally trimmed for ±1% accuracy. Requiring less
than 2mA in quiescent current, this device can deliver in excess of 10mA
with total load- and line-induced tolerances of less than 0.5%. In additon
to voltage accuracy, internal trimming achieves a temperature coefficient
of output voltage of typically 10 ppm/ C. As a result, these references are
excellent choices for application to critical instrumentation and D-to-A
converter systems.
The SG1503 is specified for operation over the full military ambient
temperature range of -55 C to 125 C , while the SG2503 is designed for
-25 C to 85 C and the SG3503 for commercial applications of 0 C to 70 C.
