Application Information (continued)

8.1.1 Temperature Sensing Applications

The AMC7836 device contains one local temperature and five unipolar analog inputs that are easily configurable

to interface with remote temperature-sensor circuits. The integrated temperature sensor and analog input

registers automatically update with every conversion. Figure 116 shows an example of a remote temperature

sensor connection.

The selected temperature sensor is the LM50 device, a high precision integrated-circuit temperature sensor that

operates in the –40°C to 125°C temperature range using a single positive supply. The full-scale output of the

temperature sensor ranges from 100 mV to 1.75 V for the operational temperature range. In an extremely noisy

environment, additional filtering is recommended. A typical value for the bypass capacitor is 0.1 µF from the V+

pin to GND. A high-quality ceramic type NP0 or X7R is recommended because of optimal performance across

temperature and very low dissipation factor.
