SG3503

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 c...
