A commercially available temperature transducer has the characteristics shown in Figure 4–67. Design an OP AMP circuit to interface the transducer output for temperatures ranging from −20C to 120C with a panel meter whose full-scale input range is 0 to 3 V. Use a standard 1:5-V battery as the reference source for the required bias. Develop two competing designs and discuss pros and cons of each.
