Note:

The AP358 temperature specifications are limited to 0°C < TA < +70°C.

Note:

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:

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:

10. 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:

11. 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.
