  • • ± 5 mV ( ± 0.2%) Max. Initial Tolerance (A grade) •• Power Supplies
  • • Wide Operating Current Range •• Instrumentation
  • • Low Voltage Reference 2.5V •• 8 Bit A/D, D/A Reference
  • • Max. 0.6 ΩΩ Dynamic Impedance (A grade) •• Current Loop Measurement and Control Systems
  • • Low Temperature Coefficient •• Reference for 5V Systems GENERAL DESCRIPTION The AMS1009 is a precision band-gap voltage reference diode. This voltage reference features a very low dynamic impedance and good temperature coefficient, operating over a wide current range of 400 µ A to 10mA. On-chip trimming is used to provide tight tolerance and minimize temperature drift. A third terminal allows the reference voltage to be adjusted to ±5% to calibrate out system errors. The AMS1009 is used as a precision 2.5V low voltage reference for digital voltmeters, power supplies or op amp circuitry, and the 2.5V make it easy to obtain a stable reference from 5V logic supplies. The AMS1009 is available in TO-92 and SO-8 packages operating over a 0 °C to 70 °C temperature range. ORDERING INFORMATION: TOL.

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, T j max is +125°C Thermal Resistance TO-92 SO-8 ϕ JA (junction to ambient) 170°C/W (0.125” leads) 165°C/W Note 3: Parameters identified with boldface type apply at temperature extremes. All other numbers apply at T A = T J = 25°C. Note 4: 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.
