SG1503/SG2503/SG3503
PRECISION 2.5-VOLT REFERENCE
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.
FEATURES
• Output voltage trimmed to ±1%
• Input voltage range of 4.5 to 40V
• Temperature coefficent of 10ppm/°C
• Quiescent current typically 1.5mA
• Output current in excess of 10mA
• Interchangeable with MC1503 and AD580
HIGH RELIABILITY FEATURES - SG1503
♦ Available to MIL-STD-883 and DESC SMD
♦ Radiation data available
♦ LMI level "S" processing available
