Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under Recommended Operating
Conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
All voltage values (except differential voltages and VCC specified for the measurement of IOS) are with respect to the network GND.
Differential voltages are at IN+, with respect to IN−.
Short circuits from outputs to VCC can cause excessive heating and eventual destruction.

Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
Maximum power dissipation is a function of TJ(max), RθJA, and TA. The maximum allowable power dissipation at any allowable ambient
temperature is PD = (TJ(max) – TA)/RθJA. Operating at the absolute maximum TJ of 150°C can affect reliability.

7 Detailed Description
7.1 Overview
These devices consist of four independent high-gain frequency-compensated operational amplifiers that are
designed specifically to operate from a single supply over a wide range of voltages. Operation from split supplies
also is possible if the difference between the two supplies is 3 V to 32 V (3 V to 26 V for the LM2902 device),
and VCC is at least 1.5 V more positive than the input common-mode voltage. The low supply-current drain is
independent of the magnitude of the supply voltage.
Applications include transducer amplifiers, DC amplification blocks, and all the conventional operational-amplifier
circuits that now can be more easily implemented in single-supply-voltage systems. For example, the LM124
device can be operated directly from the standard 5-V supply that is used in digital systems and provides the
required interface electronics, without requiring additional ±15-V supplies.
