LM107/LM207/LM307 Operational Amplifiers
General Description
The LM107 series are complete, general purpose operational amplifiers, with the necessary frequency compensation
built into the chip. Advanced processing techniques make
the input currents a factor of ten lower than industry standards like the 709. Yet, they are a direct, plug-in replacement for the 709, LM101A and 741.
The LM107 series offers the features of the LM101A, which
makes its application nearly foolproof. In addition, the device provides better accuracy and lower noise in high impedance circuitry. The low input currents also make it particularly well suited for long interval integrators or timers, sample 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

55§Ctoa125§C temper-
ature range, the LM207 from

LM307 from 0
