DESCRIPTION
The LM1458 and the LM1558 are general purpose dual operational amplifiers. The two amplifiers share a
common bias network and power supply leads. Otherwise, their operation is completely independent.
The LM1458 is identical to the LM1558 except that the LM1458 has its specifications guaranteed over the
temperature range from 0°C to +70°C instead of
−55°C
to +125°C.

See AN-450 “Surface Mounting Methods and Their Effect on Product Reliability” for other methods of soldering surface mount devices.
“Absolute Maximum Ratings” indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not guarantee specific performance limits.
The maximum junction temperature of the LM1558 is 150 C, while that of the LM1458 is 100 C. For operating at elevated temperatures,
devices in the LMC package must be derated based on a thermal resistance of 150°C/W, junction to ambient or 20°C/W, junction to
case. For the PDIP the device must be derated based on a thermal resistance of 187°C/W, junction to ambient.
For supply voltages less than ±15V, the absolute maximum input voltage is equal to the supply voltage.
Human body model, 1.5 kΩ in series with 100 pF.
