The LM158 series consists of two independent, high gain,

internally frequency compensated operational amplifiers

which were designed specifically to operate from a single

power supply over a wide range of voltages. Operation from

split power supplies is also possible and the low power

supply current drain is independent of the magnitude of the

power supply voltage. -The LM158 series consists of two independe nt, high gain, internally frequency compensated operationa l amplifiers which were designed specifically to operate from a single power supply over a wide range of voltages.
