SG1503/SG2503/SG3503 PRECISION 2.5-VOLT REFERENCE DESCRIPTION FEATURES 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 -55C to 125C , while the SG2503 is designed for -25C to 85C and the SG3503 for commercial applications of 0C to 70C. Available to MIL-STD-883 and DESC SMD Radiation data available LMI level "S" processing available 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 FUNCTIONAL DIAGRAM LINFINITY 4/90 Rev 1.2 9/96 Copyright 1996 1 Microelectronics Inc. 11861 Western Avenue Garden Grove, CA 92841 (714) 898-8121 FAX: (714) 893-2570 SG1503/SG2503/SG3503 ABSOLUTE MAXIMUM RATINGS (Note 1) Input Voltage ....................................................................... 40V Storage Temperature Range ............................. -65C to 150C Operating Junction Temperature Hermetic (T, Y - Package) ............................................. 150C Plastic (M, DM - Package) ............................................ 150C Lead Temperature (Soldering, 10 Seconds) .................. 300C Note 1.
