SG3503M

精密2.5伏参考 PRECISION 2.5-VOLT REFERENCE

Key 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 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.
