The LM107 series are complete, general purpose operation-
al amplifiers, with the necessary frequency compensation
built into the chip. Advanced processing techniques make
the input currents a factor of ten lower than industry stan-
dards like the 709. Yet, they are a direct, plug-in replace-
ment for the 709, LM101A and 741.
The LM107 series offers the features of the LM101A, which
makes its application nearly foolproof. In addition, the de-
vice provides better accuracy and lower noise in high im-
pedance circuitry. The low input currents also make it partic-
ularly well suited for long interval integrators or timers, sam-
ple and hold circuits and low frequency waveform genera-
tors. Further, replacing circuits where matched transistor
pairs buffer the inputs of conventional IC op amps, it can
give lower offset voltage and drift at a lower cost.
The LM107 is guaranteed over a b55§Cto a125§C temper-
ature range, the LM207 from b25§Cto a85§C and the
LM307 from 0§Cto a70§C.
