LOW POWER DUAL OPERATIONAL AMPLIFIERS
General Description
Features
The AZ358 consists of two independent, high gain and
internally frequency compensated operational amplifiers, it is specifically designed to operate from a single
power supply. Operation from split power supply is
also possible and the low power supply current drain is
independent of the magnitude of the power supply
voltages.

Note 1: Stresses greater than 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 Operation Ratings" is not implied. Exposure to "Absolute Maximum Ratings" for extended periods may affect device reliability.
Note 2: 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 VCC 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
25oC)
Note 3: Short circuits from the output to VCC can cause excessive heating and eventual destruction. When considering short circuits to ground, the maximum output current is approximately 40mA independent of the magnitude
of VCC. At values of supply voltage in excess of +12V, continuous short-circuits can exceed the power dissipation
ratings and cause eventual destruction. Destructive dissipation can result from simultaneous shorts on all amplifiers.

Note 4: The direction of the input current is out of the IC 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 5: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by
more than 0.3V (at 25oC). The upper end of the common-mode voltage range is VCC - 1.5V (at 25oC), but either
or both inputs can go to +18V without damages, independent of the magnitude of the VCC.
Note 6: Due to proximity of external components, insure that coupling is not originating via stray capacitors
between these external parts. This typically can be detected as this type of capacitance increases at higher frequencies.
