LOW POWER DUAL OPERATIONAL AMPLIFIERS
General Description
Features
The AP358 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.
•
•
•
Internally frequency compensated for unity gain
Large dc voltage gain: 100 dB
Very low supply current drain (500µA)-essentially
independent of supply voltage
Wide bandwidth (unity gain): 1 MHz (temperature
compensated)
•
•
•
Input common-mode voltage range includes ground
Differential input voltage range equal to the power
supply voltage
Low input offset voltage: 2mV
Wide power supply range:
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 AP358 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.
•
•
Single supply: 3V to 32V
Or dual supplies: ±1.5V to ±16V
Large output voltage swing: 0V to V+ - 1.5V

Note 2: For operating at high temperatures, the AP358 must be derated based on a +125°C maximum junction temperature and a
thermal resistance of 120°C/W for DIP and 189°C/W for Small Outline package, which applies for the device soldered in a
printed circuit board, operating in a still air ambient. The dissipation is the total of both amplifiers—use external resistors,
where possible, to allow the amplifier to saturate or to reduce the power which is dissipated in the integrated circuit.
Note 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 40mA 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.
Note 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).
Note 5: The AP358 temperature specifications are limited to 0°C < TA < +70°C.
Note 6: VO
≅
1.4V, RS = 0Ω with V+ from 5V to 30V; and over the full input common-mode range (0V to V+ -1.5V) at 25°C.
Note 7: 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 8: The input common-mode voltage of either input signal voltage should not be allowed to go negative by more than 0.3V (at
25°C). The upper end of the common-mode voltage range is V+ -1.5V (at 25°C), but either or both inputs can go to +32V
without damage, independent of the magnitude of V+.
Note 9: 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 capacitance increases at higher frequencies.

LOW POWER DUAL OPERATIONAL AMPLIFIERS
Application Information
The AP358 series are op amps which operate with only a
single power supply voltage, have true-differential inputs, and
remain in the linear mode with an input common-mode voltage of
0 VDC. These amplifiers operate over a wide range of power
supply voltage with little change in performance characteristics.
At 25°C amplifier operation is possible down to a minimum supply
Capacitive loads which are applied directly to the output of
the amplifier reduce the loop stability margin. Values of 50pF can
be accommodated using the worst-case non-inverting unity gain
connection. Large closed loop gains or resistive isolation should
be used if larger load capacitance must be driven by the
amplifier.
voltage of 2.3 VDC
.
The bias network of the AP358 establishes a drain current
Precautions should be taken to insure that the power
supply for the integrated circuit never becomes reversed in
polarity or that the unit is not inadvertently installed backwards in
a test socket as an unlimited current surge through the resulting
forward diode within the IC could cause fusing of the internal
conductors and result in a destroyed unit.
which is independent of the magnitude of the power supply
voltage over the range of 3 VDC to 30 VDC
.
Output short circuits either to ground or to the positive
power supply should be of short time duration. Units can be
destroyed, not as a result of the short circuit current causing
metal fusing, but rather due to the large increase in IC chip
dissipation which will cause eventual failure due to excessive
function temperatures. Putting direct short-circuits on more than
one amplifier at a time will increase the total IC power dissipation
to destructive levels, if not properly protected with external
dissipation limiting resistors in series with the output leads of the
amplifiers. The larger value of output source current which is
available at 25°C provides a larger output current capability at
elevated temperatures (see typical performance characteristics)
than a standard IC op amp.
Large differential input voltages can be easily
accommodated and, as input differential voltage protection
diodes are not needed, no large input currents result from large
differential input voltages. The differential input voltage may be
larger than V+ without damaging the device. Protection should be
provided to prevent the input voltages from going negative more
than -0.3 VDC (at 25°C). An input clamp diode with a resistor to
the IC input terminal can be used.
To reduce the power supply current drain, the amplifiers
have a class A output stage for small signal levels which converts
to class B in a large signal mode. This allows the amplifiers to
both source and sink large output currents. Therefore both NPN
and PNP external current boost transistors can be used to extend
the power capability of the basic amplifiers. The output voltage
needs to raise approximately 1 diode drop above ground to bias
the on-chip vertical PNP transistor for output current sinking
applications.
The circuits presented in the section on typical
applications emphasize operation on only a single power supply
voltage. If complementary power supplies are available, all of the
standard op amp circuits can be used. In general, introducing a
pseudo-ground (a bias voltage reference of V+/2) will allow
operation above and below this value in single power supply
systems. Many application circuits are shown which take
advantage of the wide input common-mode voltage range which
includes ground. In most cases, input biasing is not required and
input voltages which range to ground can easily be
accommodated.
For ac applications, where the load is capacitively coupled
to the output of the amplifier, a resistor should be used, from the
output of the amplifier to ground to increase the class A bias
current and prevent crossover distortion. Where the load is
directly coupled, as in dc applications, there is no crossover
distortion.
