High precision AD584L voltage reference module reference voltage source
AD584 eight pins is a precision reference voltage source, provides programmable
four common output voltage: 10.000 V, 7.500 V, 5.000 V and 5.000 V. The input
voltage range of 4.5 V to 30 V. This device adopts the technology of the laser
wafer to adjust the output level of programming to adjust the pin and the
temperature coefficient, thereby gaining the most flexible single chip, high
precision reference voltage source. AD584 recommended used for outside precision
reference voltage source 12 or 14 d/a (DAC)/module reference voltage source
converter (ADC), its performance is superior to the standard usually detached
benchmark voltage source.
Circuit board features:
1. 15 v onboard battery, we know that the noise of the battery is the
lowest, enable it to pure static, stable output voltage provide reliable
guarantee,
2. The board has four programming terminal, each terminal corresponding to
an output voltage, short circuit by short circuit blocks corresponding terminal
can have the corresponding voltage. Because AD584 programming pin when
programming the short circuit resistance can affect the output voltage, in order
to reduce short circuit resistance, use two terminals in parallel. With the
benefits of the alternative switch terminal is more reliable and flexible, short
circuit resistance can be smaller.
3. The temperature coefficient of 5 PPM / ° C (maximum, 0 ° C to 70 ° C,
AD584L) 15 PPM / ° C (maximum, and 55 ° C to + 125 ° C, AD584T)
4. The power consumption, static current: 1 mA (maximum), low static
current is very suitable for batteries.
5. Load capacity: 10 mA
6. Working voltage: 4.5 V to 30 V, attention, working voltage required is
higher than the output voltage.
7. The temperature range: AD584J/K/L the rated operating temperature range
of 0 ° C to + 70 ° C, AD584S/T is 55 ° C to + 125 ° C.
8. With an external power supply interface, need more than 11 v dc voltage.
9. Reference voltage output interface using pure copper 2 mm test, persons
possessing the multimeter measure pen or other instrument calibration, etc.
10. Each board before leaving the factory with a Aglient six and a half
multimeter for testing, and the output voltage, the convenient user use.
11. A multimeter and the board before testing warmed up at least 30 minutes
at room temperature is 25 degrees, guarantees the detection accuracy.
Here are six and a half multimeter measured 2.5 V voltage output effect, 2.49978
V and the standard error is very small.
