21. Temperature monitor measures three thermal zones
    Susan Pratt
    Measurement Analog Devices ADG708
    You can use an ADT7461 single-channel temperature monitor; an ADG708 low-voltage, low-leakage CMOS 8-to-1 multiplexer; and three standard 2N3906 p-n-p transistors to measure the temperature of three separate remote thermal zones (Figure 1). ...

22. Adding Hysteresis for Smooth Undervoltage and Overvoltage Lockout
    Pinkesh Sachdev
    Supply Analog Devices LTC4365
    Resistive dividers attenuate high voltages down to a level that low voltage circuits can accommodate without getting overdriven or damaged. In power path control circuits, resistive dividers help set up power supply undervoltage and overvoltage ...
