DESCRIPTION

The LM101A is a general-purpose operational
amplifier. This amplifier offers many features :
supply voltages from

±

5 V to

±

22 V, low current

drain, overload protection on the input and output,
no latch-up when the common-mode range is ex-
ceeded, freedom from oscillations and compensa-
tion with a single 30pF capacitor. It has advantages
over internally compensated amplifiers in that the
compensation can be tailored to the particular appli-
cation : slew rates of 10 V/

µ

s and bandwidths of

3.5MHz can be easily achieved.
