Operational Amplifier
Description:
These devices are monolithic operational amplifiers intended for general–purpose applications. Op-
eration is completely specified over the range of voltages commonly used for these devices. The de-
sign, in addition to providing high gain, minimizes both offset voltages and bias currents. Further, the
class–B output stage gives a large output capability with minimum power drain.
External components are used to frequency compensate the amplifier. Although the unity–gain com-
pensation network specified will make the amplifiers unconditionally stable in all feedback configura-
tions, compensation can be tailored to optimize high–frequency performance for any gain setting.
The fact that the amplifiers are built on a single silicon chip provides low offset and temperature drift
at minimum cost. It also ensures negligble drift due to temperature gradients in the vicinity of the am-
plifier.

Note 1 For operating at elevated temperatures, the device must be derated based on a 100°C maxi-
mum junction temperature and a thermal resistance 150°C/W junction to ambient or 45°C/W,
junction to case for the metal can package.
