General Description
The LH0062/LH0062C is a precision, high speed FET input operational amplifier with more than an order of magnitude improvement in slew rate and bandwidth over conventio[lal FET IC op amps. In addition it features very cioselymatched input characteristics, very high input impedance, and ultra low input currents with no compromise in noise, common mode rejection ratio or open loop gain. The device has internal unity gain frequency compensation, thus assuring stability in all normal applications. 'This considerably simplifies its application, since no external components are necessary for operation. However, unlike most internally compensated amplifiers, external fre~ quency compensation may be added for optimum performance. For inverting applications, feedforward compensation will boost the slew rate to over 120 V/J.1.S and almost double the bandwidth. (See LB-2; LB-14,.
