  • • Low Tem perature Coefficient •• Battery Powered Systems
  • • Wide Operating Current Range •• Instrumentation AMS04…………………….15 µµA to 20mA •• A/D, D/A Converters
  • • Max. 1 ΩΩ Dynamic Impedance •• Power Sup plies
  • • Typ. 2% Output tolerance •• 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 dynam ic 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 it s 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 a nd 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 a nd test conditions, see the Electrical Characteristics . The guaranteed specifications apply only for the test conditions listed. Note 2: For elevated temperature operation, T J max is +100°C Thermal Resistance TO - 92 SO - 8 ϕ JA (junction to ambient) 1 70°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 T MAX and T MIN , divided by T MAX - T MIN . The measured temperatures are 0 °C , 25 °C and 70 °C.
