Advanced Monolithic Systems AMS04/AMS05 VOLTAGE REFERENCES FEATURES APPLICATIONS • Low Temperature Coefficient • Wide Operating Current Range AMS04…………………….15µ µ A to 20mA AMS05…………………….20µ µ A to 20mA • Max. 1Ω Ω Dynamic Impedance • Typ. 2% Output tolerance • Battery Powered Systems • Instrumentation • A/D, D/A Converters • Current sources • Power Supplies • Telecommunication GENERAL DESCRIPTION The AMS04 and the AMS05 are two-terminal, band-gap voltage reference diodes, with an output voltage of 1.25V for the AMS04 and 2.5V for the AMS05. These devices feature low dynamic impedance and good temperature coefficient, operating over a wide current range. Since the band-gap reference of these devices uses only transistors and resistors, low noise and good long term stability result. The wide dynamic operating range allows its use with widely varying supplies with excellent regulation. The AMS04 and AMS05 can be used for portable meters, regulators, data acquisition converters and telecommunication. The AMS04 and AMS05 are operational over a temperature range of 0°C to 70°C and are available in TO-92 and SO-8 packages. ORDERING INFORMATION: MAX.

Operating Ratings indicate conditions for which the device is intended to be functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Note 2: For elevated temperature operation, TJ max is +100°C Thermal Resistance TO-92 ϕ JA (junction to ambient) SO-8 170°C/W (0.125” leads) 165°C/W Note 3: The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between the operating TMAX and TMIN, divided by TMAX - TMIN. The measured temperatures are 0°C, 25°C and 70°C.
