DESCRIPTION
The LM101A is a general purpose operational amplifier which offers many features: supply voltages
from ±5V to ±22V, low current drai n, overload protection on the inpu t and outpu t, no latch-up when
the common-mode range is ex ceeded, free from
oscillations and compensation with a single 30pF
capacitor. It has advantages over internally compensated amplifiers in that t he compen sation can
be tailored to the particular application: slew rate
of 10V/µs and bandwidth of 3.5MHz can be easily
achieved.
