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 generators.
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§C to a125§C temperature
range, the LM207 from b25§C to a85§C and the
LM307 from 0§C to a70§C.
Features
Y Offset voltage 3 mV maximum over temperature
Y Input current 100 nA maximum over temperature
Y Offset current 20 nA maximum over temperature
Y Guaranteed drift characteristics
