We found this circuit in a 1967 documentation. The integrated circuit and an operational one of the time. Modern equivalents can be tried out. The power supply is symmetrical.
With this configuration we have a voltage follower, amplifier with unit gain, in which the output...
This circuit is from the Linear Circuits Application of Texas Instruments, using an operational amplifier...
This amplifier, suggested by National Semiconductor (Now Texas Instruments), has high input...
