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.
