Description
The LM158W, LM258W, and LM358W circuits
consist of two independent, high-gain, operational
amplifiers (op amps), which employ internal
frequency compensation and are specifically
designed to operate from a single power supply
over a wide range of voltages. The low-power
supply drain is independent of the power supply
voltage magnitude. Application areas include
transducer amplifiers, DC gain blocks, and all the
conventional op amp circuits, which can now be
more easily implemented in single power supply
systems. For example, these circuits can be
directly supplied with the standard +5 V, which is
used in logic systems and easily provide the
required interface electronics with no additional
power supply. In linear mode, the input common
mode voltage range includes ground. The output
voltage can also swing to ground, even though
operated from a single power supply voltage.
