LM101A LM201A LM301A Operational Amplifiers
General Description
The LM101A series are general purpose operational amplifi- ceeded and freedom from oscillations and compensation
ers which feature improved performance over industry stan- with a single 30 pF capacitor It has advantages over inter-
dards like the LM709 Advanced processing techniques nally compensated amplifiers in that the frequency compen-
make possible an order of magnitude reduction in input cur- sation can be tailored to the particular application For ex-
rents and a redesign of the biasing circuitry reduces the ample in low frequency circuits it can be overcompensated
