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 b55§C to a125§C temperature range, the LM207 from b25§C to a85§C and the LM307 from 0§C to a70§C.

Note 1: The maximum junction temperature of the LM107 is 150§C, and the LM207/LM307 is 100§C. For operating at elevated temperatures, devices in the H08 package must be derated based on a thermal resistance of 165§C/W, junction to ambient, or 30§C/W, junction to case. The thermal resistance of the dual-in-line package is 100§C/W, junction to ambient.
Note 2: For supply voltages less than g15V, the absolute maximum input voltage is equal to the supply voltage.
Note 3: These specifications apply for g5V s VS s a20V and b55§C s TA s a125§C for the LM107 or b25§C s TA a85§C for the LM207, and 0§C s TA s a70§C and g5V s VS s g15V for the LM307 unless otherwise specified.
Note 4: Refer to RETS107X for LM107H and LM107J military specifications.
