(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. For ensured specifications and test conditions, see the
Electrical Characteristics. The ensured specifications apply only for the test conditions listed. Some performance characteristics may
degrade when the device is not operated under the listed test conditions.
(2) The maximum power dissipation must be derated at elevated temperatures and is dictated by TJmax (maximum junction temperature),
θJA (package junction to ambient thermal resistance), and TA (ambient temperature). The maximum allowable power dissipation at any
temperature is PDmax = (TJmax - TA)/θJA or the number given in the Absolute Maximum Ratings, whichever is lower.
(3) Short circuits from the output to V+ can cause excessive heating and eventual destruction. When considering short circuits to ground,
the maximum output current is approximately 40 mA independent of the magnitude of V+. At values of supply voltage in excess of +15V,
continuous short-circuits can exceed the power dissipation ratings and cause eventual destruction. Destructive dissipation can result
from simultaneous shorts on all amplifiers.
(4) 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
also lateral NPN parasitic 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 for a 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 (at 25°C).

DESCRIPTION
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.
Application areas include transducer amplifiers, dc gain blocks and all the conventional op amp circuits which now can be more easily implemented in single power supply systems. For example, the LM158 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 without requiring the additional ±15V power supplies.

FEATURES
• Available with Radiation Specification
   – High Dose Rate 100 krad(Si)
   – ELDRS Free 100 krad(Si)
• Internally Frequency Compensated for Unity Gain
• Large DC Voltage Gain: 100 dB
• Wide Bandwidth (Unity Gain): 1 MH
   z(Temperature Compensated)
• Wide Power Supply Range:
   – Single Supply: 3V to 32V
   – Or Dual Supplies: ±1.5V to ±16V
• Very Low Supply Current Drain (500 μA) − Essentially Independent of Supply Voltage
• Low Input Offset Voltage: 2 mV
• Input Common-mode Voltage Range Includes Ground
• Differential Input Voltage Range Equal to the Power Supply Voltage
• Large Output Voltage Swing: 0V to V+ − 1.5V

UNIQUE CHARACTERISTICS
• In the Linear Mode the Input Common-Mode Voltage Range Includes Ground and the Output Voltage can also Swing to Ground, even though Operated from only a Single Power Supply Voltage.
• The Unity Gain Cross Frequency is Temperature Compensated.
• The Input Bias Current is also Temperature Compensated.

ADVANTAGES
• Two Internally Compensated Op Amps
• Eliminates Need for Dual Supplies
• Allows Direct Sensing Near Gnd and VO also Goes to Gnd
