LTC2408

The need to measure a wide variety of physical phenomena is increasingly important in intelligent sensors. The following circuit gives eight examples of the flexibility of the LTC2408 for sensing real-world phenomena. The eight inputs of the LTC2408 are used here in a variety of ways that would not be practical without the dynamic range of the LTC2408 (see Figure 345.1).
