Prefixes: LM1, LM2, and LM3 refer to temperature range 2. Suffix A refers to enhanced Vio performance 3. Suffix W refers to enhanced ESD ratings. Description The LM124, LM224x and LM324x consist of four independent, high gain operational amplifiers with frequency compensation implemented internally. They 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.

Neither of the input voltages must exceed the magnitude of (VCC +) or (VCC -). 2. Short-circuits from the output to VCC can cause excessive heating if VCC > 15 V. The maximum output current is approximately 40 mA independent of the magnitude of VCC. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 3. This input current only exists when the voltage at any of the input leads is driven negative. It is due to the collector-base junction of the input PNP transistor becoming forward biased and thereby acting as an input diode clamp. In addition to this diode action, there is also an NPN parasitic action on the IC chip. This transistor action can cause the output voltages of the op amps to go to the VCC voltage level (or to ground for a large overdrive) for the time during which an input is driven negative. This is not destructive and normal output starts up again for input voltages higher than -0.3 V. 4. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous shortcircuits on all amplifiers. These are typical values given for a single layer board (except for TSSOP which is a two-layer board). 5. Human body model: 100 pF discharged through a 1.5 kΩ resistor between two pins of the device, done for all couples of pin combinations with other pins floating. 6. Machine model: a 200 pF cap is charged to the specified voltage, then discharged directly between two pins of the device with no external series resistor (internal resistor < 5 Ω), done for all couples of pin combinations with other pins floating.
