AD592  
To minimize the number of MUXs required when a large num-  
ber of AD592s are being used, the circuit can be configured in a  
matrix. That is, a decoder can be used to switch the supply volt-  
age to a column of AD592s while a MUX is used to control  
which row of sensors are being measured. The maximum num-  
ber of AD592s which can be used is the product of the number  
of channels of the decoder and MUX.  
To convert the AD592 output to °C or °F a single inexpensive  
reference and op amp can be used as shown in Figure 17. Al-  
though this circuit is similar to the two temperature trim circuit  
shown in Figure 6, two important differences exist. First, the  
gain resistor is fixed alleviating the need for an elevated tem-  
perature trim. Acceptable accuracy can be achieved by choosing  
an inexpensive resistor with the correct tolerance. Second, the  
AD592 calibration error can be trimmed out at a known conve-  
nient temperature (i.e., room temperature) with a single pot ad-  
justment. This step is independent of the gain selection.  
An example circuit controlling 80 AD592s is shown in Figure  
16. A 7-bit digital word is all that is required to select one of  
the sensors. The enable input of the multiplexer turns all the  
sensors off for minimum dissipation while idling.
