AMS3100A-2.5

Advanced Monolithic Systems AMS3100A-2.5 MICROPOWER VOLTAGE REFERENCE FEATURES ±12 mV (±0.5%) max. initial tolerance (A grade) Operating Current 20µA to 20mA Low Voltage Reference 2.50V Max. 0.5Ω Dynamic Impedance (A grade) Low Temperature Coefficient SOT-23 Package Available ±5% Output Voltage Precission Trimming Low cost APPLICATIONS Battery Powered Systems Instrumentation A/D, D/A Converters Temperature measurement Current sources Notebook/Personal Computer Monitors/ VCR/ TV Pagers GENERAL DESCRIPTION The AMS3100A-2.5 are two-terminal micropower band-gap voltage reference that feature a very low dynamic impedance and good temperature coefficient, operating over a 20µA to 20mA current range. AMS3100A-2.5 is trimmed at wafer test level to optimize the temperature coefficient and tight output voltage tolerance. The advanced process technology used, makes the AMS3100A-2.5 exceptionally tolerant of capacitive loading, making it easy to use in almost any reference application. The wide dynamic operating range allows its use with widely varying supplies with excellent regulation. The extremely low power drain, makes these reference diodes useful for micropower circuitry. These voltage references can be used to make portable meters, regulators or general purpose analog circuitry with battery life approaching shelf life. Further more, the wide operating current allows it to replace older references with a tight tolerance part. A third terminal al...
