General Description
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/V
the popular MC1558 dual operational amplifier.
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 Volts or as high as 32 Volts
with quiescent currents about one fifth of those associated with the LM741 (on a pet 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.
