Utilizing the circuit designs perfected for recently introduced Quad
Operational Amplifiers, these dual operational amplifiers feature 1) low
power drain, 2) a common mode input voltage range extending to
ground/VEE, 3) single supply or split supply operation and 4) pinouts
compatible with the popular MC1558 dual operational amplifier. The LM158
series is equivalent to one?half of an LM124.
These amplifiers have several distinct advantages over standard
operational amplifier types in single supply applications. They can operate at
supply voltages as low as 3.0 V or as high as 32 V, with quiescent currents
about one?fifth of those associated with the MC1741 (on a per amplifier
basis). The common mode input range includes the negative supply, thereby
eliminating the necessity for external biasing components in many
applications. The output voltage range also includes the negative power
supply voltage.
