GENERAL DESCRIPTION

The AMSREF-02 is a precision voltage reference, which provides a stable +5V, which can be adjusted over a ± 6% range

with minimal effect on temperature stability. Careful design of this device improved its bandgap and as a result excellent

temperature stability is achieved. The operating supply range is 7V to 40V with a typical current drain of 650µA.

Low cost, low noise and low power makes the AMSREF-02 an excellent choice whenever a stable voltage reference is

required. Applications include D/A and A/D converters, portable instrumentation and digital voltmeters. The versatility of

AMSREF-02 is enhanced by its use as a monolithic temperature transducer.

The AMSREF-02 is operational in the full industrial temperature range of -40°C to 85°C and is available in the 8 lead SOIC

and plastic dip (PDIP) packages.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. 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: The output voltage change with temperature (∆VOT) is defined as the absolute difference between the maximum output voltage and the minimum output

voltage over the specified temperature range expressed as a percentage of 5V:

∆VOT = [(VMAX -VMIN)/ 5V] x 100

Note 3: ∆VOT specification applies trimmed to +5.000V or untrimmed

Note 4: TCVO is defined as ∆VOT divided by the temperature range: TCVO (-40°C to +85°C)= [∆VOT (-40°C to +85°C)] / 125°C

Note 5: Line and Load Regulation specifications include the effect of self heating.

Note 6: During sink current test, the device meets the output voltage specified.

Note 7: Limit current in or out of pin 3 to 50nA and capacitance on pin 3 to 30pF.

OUTPUT ADJUSTMENT

The REF-02 trim terminal can be used to adjust the 5 Volt output

voltage ± 300mV. This feature allows the system designer to trim

system errors by setting the reference to a voltage other than 5V.

The system can also be set exactly 5.000V, or to 5.12V for binary

applications.

Adjustment of the output does not significantly affect the

temperature performance of the device. The temperature

coefficient change is approximately 0.7ppm/°C for 100mV of

output adjustment.
