NOTE

Either placement of resistor as shown in Figure 2 and Figure 3 is just as effective.

8.2 Typical Applications

8.2.1 Full-Range Centigrade Temperature Sensor

Figure 4. Full-Range Celsius (Centigrade) Temperature Sensor (

−55°C to 130°C)

8.2.1.1 Design Requirements

Because the LMT88 is a simple temperature sensor that provides an analog output, design requirements related

to layout are important, refer to Layout for detailed description.

8.2.1.2 Detailed Design Procedure

The LMT88 output follows Equation 5.
