... PIN 2 CAN BE EITHER ATTACHED OR UNCONNECTED * BOTTOM VIEW PRODUCT HIGHLIGHTS 1. With a single supply ( the AD592 offers 0.5 C temperature measurement accuracy wide operating temperature range (– +105 C) and highly linear output make the AD592 an ideal sub- stitute for older, more limited sensor technologies (i.e., thermistors, RTDs, diodes, thermocouples). 3. The AD592 is electrically rugged ...

... C to +70 C and – +105 C. These specifications cor- respond to the actual error the user would see if the current out- put of an AD592 were converted to a voltage with a precision resistor. Note that the maximum error at room temperature, over the commercial IC temperature range extended range including the boiling point of water, can be directly read from the specifications table ...

... In free air applications a clip-on heat sink will decrease output stabilization time by 10-20%. MOUNTING CONSIDERATIONS If the AD592 is thermally attached and properly protected, it can be used in any temperature measuring situation where the maximum range of temperatures encountered is between –25 C and +105 C. Because plastic IC packaging technology is em- ployed, excessive mechanical stress must be safeguarded against when fastening the device with a clamp or screw-on heat tab ...

... 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. An example circuit controlling 80 AD592s is shown in Figure 16 ...
