Note 1:
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 2:
Short circuits from the output to V
can cause excessive heating and eventual destruction. When considering short cirucits 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 3:
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 4:
The AP358 temperature specifications are limited to 0°C < T
A
< +70°C.
Note 5:

1.4V, R
S
= 0
with V
from 5V to 30V; and over the full input common-mode range (0V to V
+
-1.5V) at 25°C.
Note 6:
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 7:
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 8:
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.
