... This protects not only the MAX378/MAX379 and the circuitry they drive, but also the sensors or signal sources that drive the muxes. The series N-channel/P-channel/N-channel protection structure has two significant advantages over the simple current-limiting protection scheme of the industry’ ...

... ZERO REFERENCE V- -15V Figure 6. Typical Data Acquisition Front End _______________Typical Applications Figure 6 shows a typical data acquisition system using the MAX378 multiplexer. Since the multiplexer is driving a high-impedance input, its error is a func- tion of its own resistance (R ) times the multi- DS(ON) plexer leakage current (I ...

... Sample/Holds or A/Ds. Such input overdrives may also cause input-to-input shorts, allowing the high current output of one sensor to possibly damage another. The MAX378 eliminates all of the above problems. It not only limits its output voltage to safe levels, with or without power applied (V+ and V-), but also turns all channels off when power is removed ...

... In a typical data acquisition system, such as in Figure 6, the dominant delay is not the switching time of the MAX378 multiplexer, but is the set- , which turns it tling time of the following amplifiers and S/H. Another limit- GS ing factor is the RC time constant of the multiplexer ...
