Dual Comparators Match Precision Industrial, Instrumentation Application Needs (.PDF Download)

Oct. 21, 2015

Dual precision comparators are needed in many designs, such as for industrial and instrumentation applications, to generate accurate pulse-width modulated (PWM) waveforms with very high (>99%) and very low (<1%) duty-cycle percentages. This design idea (Fig. 1) improves on designs based on the common LM311 and LT1011 devices, both of which require resistor pull-ups and have asymmetric timing paths. The features of this new design include matched, short propagation delays (Tpd); accurate duty-cycle generation; push-pull, rail-to-rail output; and operation from a supply above 15 V...
