8 / 17 page 8 FN3283.8 June 13, 2006 Typical Applications Overvoltage Protection A very convenient form of overvoltage protection consists of adding two small signal diodes (1N4148, 1N914 type) in series with the supply pins (see Figure 9). This arrangement effectively blocks the flow of reverse currents. It also floats the supply pin above or below the normal V+ or V- value. In this case the overvoltage signal actually becomes the power supply of the IC. From the point of view of the chip, nothing has changed, as long as the difference V+ - (V-) doesn’t exceed 44V. The addition of these diodes will reduce the analog signal range to 1V below V+ and 1V above V-, but it preserves the low channel resistance and low leakage characteristics. Typical application information is for Design Aid Only, not guaranteed and not subject to production testing. FIGURE 7. INSERTION LOSS FIGURE 8.
