Seven Nanosecond Comparator for Single Supply Operation - AN72 Linear Technology
AN72 is an extensive discussion of the causes and cures of problems in very high speed
comparator circuits. A separate applications section uses the 7ns LT1394 in V-to-F
converters, crystal oscillators, clock skew generators, triggers, sampling
configurations and a nanosecond pulse stretcher. Appendices cover related topics. |

Synchronized Window Comparator Eliminates Error - 05/11/95 EDN-Design Ideas:
Precision A/D converters need a window comparator. The window comparator in Fig 1a is
synchronized to the clock signal. This synchronization eliminates errors that could
arise when the input signal crosses the high or low threshold (Fig 1b)unsynchronized
to clock. In operation, comparator IC1A sets flip-flop IC2.....(design idea added

Two Buttons Provide Safe Start - 07/06/00 EDN-Design Ideas: The circuit in Figure
1 provides a safety interlock that checks the actuation of two pushbuttons before
enabling a relay. When you push both buttons, the circuit actuates the relay. At that
point, you can release one of the switches without the relay'.....(design idea added

Voltage Comparator - This experiment only requires a single operational amplifier.
The model 1458 and 353 are both "dual" op-amp units, with two complete amplifier
circuits housed in the same 8-pin DIP package. I recommend that…(circuit added 6/07) |

Voltage Comparator Switch - This circuit will provide an indication whenever the
input voltage differs from two defined limits, V1 and V2. The supply voltage, Vcc must
be higher than the highest input voltage by at least 2 volts. One application here is
to monitor a 12V car battery.... (schematic added 6/07) |

Wide Band Zero Cross Detector - This circuit was designed to convert a low
amplitude 40KHz signal into a clean square wave signal. It will work with inputs
as small as 5mv peak-to-peak or as large as 3 volts peak to peak. The input
frequency can range from a few kilohertz to about 150KHz. ….(designed by David A.

Xenon Lamp Flash Detector - This circuit uses a small 2.5mm square photo diode in
conjunction with a 100mH coil to detect the short light flashes from a xenon lamp.
The coil makes the circuit immune to normal room lights. Its 10mv sensitivity
can detect light flashes from a range of over 100 feet. Reflections from a
room’s walls and ceiling is usually enough to trigger the circuit. The entire
circuit draws only 3 Microamps from a 6 to 9 volt battery. ….(designed by David A.
