Offset stability can be degraded by stray thermoelectric
voltages arising from dissimilar metals at the contacts to the
input terminals. Best operation will be obtained when both
input contacts are maintained at the same temperature,
preferably close to the temperature of the device's package.

fitted to unnulled 741series sockets. However, if conventional
741 nulling circuitry is in use, it should be modified or
removed to enable proper OP-oS operation. The OP-oS
provides stable operation with load capacitance of up to
500pF and :t 10V swings; larger capacitances should be
decoupled with a son resistor.
