Typical Applications

The sum of the AD590 currents appears across R, which is

chosen by the formula:

,

where n = the number of sensors. See Figure 8.

The AD590 produces a temperature-dependent voltage

across R (C is for ﬁltering noise). Setting R2 produces a

scale-zero voltage. For the celsius scale, make R = 1k

Ω

and VZERO = 0.273V. For Fahrenheit, R = 1.8kΩ and

VZERO = 0.460V. See Figure 9.

Meter displays current output directly in degrees Kelvin.

using the AD590J, sensor output is within

±10 degrees over

the entire range. See Figure 10.
