OP AMPS
internal schematic: note the number of transistors
OP amps
are integrated chip based amplifiers that can be used for a variety of
functions such as amplification, comparing, switching and other tasks. Why
build an amplifier circuit from many components when you can use an off
the shelf OP amp package with reliable results and economical pricing?
The LM 386 OP amp chip can
easily be configured into a
G.F.I. Schematic of GFI Circuit A GFI uses an OP amp to compare voltages from a small current transformer to detect small potentially harmful currents leaking to ground and initiating tripping of the circuit
