Abstract
The conventional integrated-circuit operational amplifier is not well suited to many system applications that operate from only a single power supply voltage. To more optimally meet the requirements of industrial control systems a new current- differencing opamp has been developed that uses a simple circuit to provide a gain element that out performs the 741 IC opamp. As a result of the circuit simplicity, multiple opamps are possible and six independent internally compensated amplifiers have been fabricated on a single 80/spl times/93-mil die. Many circuits are presented only not to show how this circuit can perform most the application functions of a standard IC opamp, but also to indicate the increased usefulness of this new input current differencing type of opamp circuit in single power-supply control system applications.Keywords
