APPLICATIONS INFORMATION
The OP07 provides stable operation with load capacitance of up
to 500 pF and ±10 V swings; larger capacitances should be
decoupled with a 50 Ω decoupling resistor.
Stray thermoelectric voltages generated by dissimilar metals at
the contacts to the input terminals can degrade drift
performance. Therefore, best operation is obtained when both
input contacts are maintained at the same temperature,
preferably close to the package temperature.
