Input voltage range equal to the power supply voltage Large output voitage swing OV to Vt 1.5V GENERAL DESCRIPTION The LM124 series consists of four 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 voitage. Application areas include transducer amplifiers, de gain. blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM124 series can.be directly operated off of the standard +5V power supply voltage which is used in digital systems and will easily provide the required interface electronics with- out requiring the additional +15V power supplies. In the linear mode the input common-mode voitage range includes ground, and the output voitage can also swing to ground, even though operated from only a single power supply voltage. The unity gain cross frequency is temperature compen- sated, as is the input bias current.

The LM124 can be derated based ona + 150C maximum junction temperature. The dissipation is the total of all four amplifiersuse external resistors, where possible, to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit. Note 2: Intersils LM124 series is protected against shorts to either V* or V-. No more than one output at a time should be shorted. At Vsuep > 15V, continuous shorts can exceed the power dissipation ratings and cause eventual destruction. Note 3: This input current will only exist when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistors becoming forward biased and thereby acting as input diode clamps. In addition to this diode action, there is alsv lateral NPN parsitic transistor action on the IC chip. This transistor action can cause the output voltages of the op amps to go to the V* voltage level (or to ground fora large overdrive) for the time duration that an input is driven negative. This is not destructive and normal output states will re-establish when the input voltage, which was negative again returns to a value greater than 0.3V. Note 4: These specifications apply for V+ =+5V and ~55C = T, = +125C for the LM124, and OC = T, = +70C for the LM324. Note : Vo = 1.4V, Rg =0N with V* from 5V to 30V, and over the full input common-mode range (OV to V* =1.5V). Note 6: The direction of the input current is out of the C due to the PNP input stage. This current is essentially constant, independent of the state of the output so no loading change exists on the input lines. Note 7: The input common-mode voitage or either input signal voltage should not be allowed to go negative by more than 0.3V. The upper end of the common-mode voltage range is V*~1.5V, but either or both inputs can go to +32V without damage. Note 8: Due to proximity of external components, insure that coupling is not originating via stray capacitance between these external parts. This typically can be detected as this type of capacitive coupting increases at higher frequencies.
