- AN-1515 A Comprehensive Study of the Howland Current Pump (Rev. A)PDF, 165 Kb, Revision: A, Datei veröffentlicht: Apr 26, 2013
It is well known to analog experts that you can use the positive and negative inputs of an operationalamplifier to make a high-impedance current source (current pump) using a conventional operationalamplifier (op amp). This basic circuit can put out both + and - output current (or zero current) into variousloads. The theory is simple. But the practical problems involved are not so simple or - AN-1684 Saving Power in an AC-Coupled Amplifier Circuit (Rev. A)PDF, 99 Kb, Revision: A, Datei veröffentlicht: Apr 26, 2013
AC-coupled circuits are often used for single supply operation to bring the input voltage into the inputrange of the amplifier. This circuit topology can be used in AC smoke detectors or in AC proximitysensors.
