AD592  
The circuit shown can be optimized for any ambient tempera-  
ture range or thermocouple type by simply selecting the correct  
value for the scaling resistor – R. The AD592 output (1 µA/K)  
times R should approximate the line best fit to the thermocouple  
curve (slope in V/°C) over the most likely ambient temperature  
range. Additionally, the output sensitivity can be chosen by  
selecting the resistors RG1 and RG2 for the desired noninverting  
gain. The offset adjustment shown simply references the AD592  
to °C. Note that the TC’s of the reference and the resistors are  
the primary contributors to error. Temperature rejection of 40  
to 1 can be easily achieved using the above technique.  
By using a differential input A/D converter and choosing the  
current to voltage conversion resistor correctly, any range of  
temperatures (up to the 130°C span the AD592 is rated for)  
centered at any point can be measured using a minimal number  
of components. In this configuration the system will resolve up  
to 1°C.  
A variable temperature controlling thermostat can easily be built  
using the AD592 in the circuit of Figure 14.

Although the AD592 offers a noise immune current output, it is  
not compatible with process control/industrial automation cur-  
rent loop standards. Figure 12 is an example of a temperature to  
4–20 mA transmitter for use with 40 V, 1 kΩ systems.

In this circuit the 1 µA/K output of the AD592 is amplified to  
1 mA/°C and offset so that 4 mA is equivalent to 17°C and  
20 mA is equivalent to 33°C. Rt is trimmed for proper reading  
at an intermediate reference temperature. With a suitable choice  
of resistors, any temperature range within the operating limits of  
the AD592 may be chosen.

RHIGH and RLOW determine the limits of temperature controlled  
by the potentiometer RSET. The circuit shown operates over the  
full temperature range (–25°C to +105°C) the AD592 is rated  
for. The reference maintains a constant set point voltage and  
insures that approximately 7 V appears across the sensor. If it is  
necessary to guardband for extraneous noise hysteresis can be  
added by tying a resistor from the output to the ungrounded  
end of RLOW.

Multiple remote temperatures can be measured using several  
AD592s with a CMOS multiplexer or a series of 5 V logic gates  
because of the device’s current-mode output and supply-voltage  
compliance range. The on-resistance of a FET switch or output  
impedance of a gate will not affect the accuracy, as long as 4 V  
is maintained across the transducer. MUXs and logic driving  
circuits should be chosen to minimize leakage current related  
errors. Figure 15 illustrates a locally controlled MUX switching  
the signal current from several remote AD592s. CMOS or TTL  
gates can also be used to switch the AD592 supply voltages,  
with the multiplexed signal being transmitted over a single  
twisted pair to the load.
