Circuit Description This circuit design is to monitor the average current in an AC line-connected load and to illuminate an LED if it exceeds a specified level. µPower, Low Voltage Comparator with Reference The basis of this design is the LT6703-2 which combines a micropower, low voltage comparator with a 400mV reference ...

A New Era in Space Products - Radiation Tolerant

T.J. Fure - Product Marketing Manager
Gabino Alonso - Strategic Marketing Engineer Mar 23rd 2016
Recent developments have made doing business in space ever more achievable to a broadening base of companies. A market previously consisting solely of major defense contractors and national governments has been disrupted by a growing list of commercial companies determined to deploy an enterprise beyond the confines of our ...

Parameters that Affect Comparator Propagation Delay Measurements

Kevin B. Scott - Senior Strategic Marketing Engineer Nov 4th 2015
One of the key specifications for a comparator is propagation delay - the amount of time it takes for a signal propagate from the comparator input to the output. Whether as a threshold detector in a battery powered application, or on a high speed signal processing board, the comparator's propagation delay is often the first ...

The comparators exhibit extremely high toggle rates of 280 MHz and very low propagation delays of only 2.9ns. An overview of important features and specifications is presented. A brief description of each of the five members of the family ...

LTC6752 Pulse Stretcher Circuit/Monostable Multivibrator

Dec 16th 2014
For detecting short pulses from a single sensor, a pulse stretcher is often required. The circuit of the figure above acts as a one-shot, stretching the width of an incoming pulse to a consistent ~100ns. The circuit works as follows: Comparator U1 functions as a threshold detector, and Comparator U2 functions as a one-shot. ...
