AD580
The consistent voltage versus temperature performance of a
typical AD580 is shown in Figure 7. Note that the characteristic
is quasi-parabolic, not the possible S type characteristics of
classical Zener references. This parabolic characteristic permits
a maximum output deviation specification over the device’s full
operating temperature range, rather than just at 3 to 5 discrete
temperatures.
The AD580M guarantees a maximum deviation of 1.75 mV
over the 0°C to 70°C temperature range. This can be shown to
be equivalent to 10 ppm/°C average maximum; i.e.,
The AD580 typically exhibits a variation of 1.5 mV over the
power supply range of 7 V to 30 V. Figure 8 is a plot of AD580
line rejection versus frequency.
NOISE PERFORMANCE
Figure 9 represents the peak-to-peak noise of the AD580 from
1 Hz (3 dB point) to a 3 dB high end shown on the horizontal
axis. Peak-to-peak noise from 1 Hz to 1 MHz is approximately
600 µV.

THE AD580 AS A CURRENT LIMITER
The AD580 represents an excellent alternative to current limiter
diodes that require factory selection to achieve a desired
current. This approach often results in temperature coefficients
of 1%/C. The AD580 approach is not limited to a specially
selected factory set current limit; it can be programmed from
1 mA to 10 mA with the insertion of a single external resistor.
The approximate temperature coefficient of current limit for the
AD580 used in this mode is 0.13%/°C for I
0.01%/°C for I

limiter for I
