LOW POWER LOW OFFSET VOLTAGE DUAL
COMPARATORS
Description
Pin Assignments
The AP393 consists of two independent precision voltage
comparators with an offset voltage specification as low as
2.0mV max for two comparators 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.
These comparators also have a unique characteristic in that
the input common-mode voltage range includes ground, even
though operated from a single power supply voltage.

generators; wide range VCO; MOS clock timers;
multivibrators and high voltage digital logic gates. The AP393
is designed to directly interface with TTL and CMOS. When
operated from both plus and minus power supplies, the
AP393 will directly interface with MOS logic where their low

Notes:
2. For operating at high temperatures, the AP393 must be derated based on a 125°C maximum junction temperature and a
thermal resistance of 170°C/W which applies for the device soldered in a printed circuit board, operating in a still air
ambient.The low bias dissipation and the “ON-OFF” characteristic of the outputs keeps the chip dissipation very small.
(PD<100mW), provided the output transistors are allowed to saturate
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 20mA independent of the magnitude of V+.
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 comparators 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 is negative,
again returns to a value greater than -0.3V.
5. The AP393 temperature specifications are limited to 0°C < TOP < +70°C.
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 reference or input lines.
7. The input common-mode voltage or either input signal voltage should not be allowed to go negative by more than 0.3V. The
upper end of the common-mode voltage range is V+-1.5V at 25°C, but either or both inputs can go to 36V without damage,
independent of the magnitude of V+.
8. The response time specified is for a 100mV input step with 5mV overdrive. For larger overdrive signals 300ns can be obtained,
see typical performance characteristics section.
9. Positive excursions of input voltage may exceed the power supply level. As long as the other voltage remains within the
common-mode range, the comparator will provide a proper output state. The low input voltage state must not be less than -0.3V
(or 0.3V below the magnitude of the negative power supply, if used).
10. At output switch point, 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.

COMPARATORS
Application Information
The AP393 is high gain, wide bandwidth devices, like most comparators, can easily oscillate if the output
lead is inadvertently allowed to capacitively couple to the inputs via stray capacitance. This shows up only during
the output voltage transition intervals as the comparator change states. Power supply bypassing is not required
to solve this problem. Standard PC board layout is helpful as it reduces stray input-output coupling. Reducing the
input resistors to < 10kΩ reduces the feedback signal levels and finally, adding even a small amount (1.0 to
10 mV) of positive feedback (hysteresis) causes such a rapid transition that oscillations due to stray feedback
are not possible. Simply socketing the IC and attaching resistors to the pins will cause input-output oscillations
during the small transition intervals unless hysteresis is used. If the input signal is a pulse waveform, with
relatively fast rise and fall times, hysteresis is not required. All input pins of any unused comparators should be
tied to the negative supply.
The bias network of the AP393 establishes a drain current independent of the magnitude of the power
supply voltage over the range of from 2.0 VDC to 30 VDC. It is usually unnecessary to use a bypass capacitor
across the power supply line.
The differential input voltage may be larger than V+ without damaging the device (Note 11). Protection
should be provided to prevent the input voltages from going negative more than -0.3 VDC (at 25°C). An input
clamp diode can be used as shown in the applications section.
The output of the AP393 is the uncommitted collector of a grounded-emitter NPN output transistor. Many
collectors can be tied together to provide an output OR’ing function. An output pull-up resistor can be connected
to any available power supply voltage within the permitted supply voltage range and there is no restriction on this
voltage due to the magnitude of the voltage applied to the V+ terminal of the AP393 package. The output can
also be used as a simple SPST switch to ground (when a pull-up resistor is not used). The amount of current the
output device can sink is limited by the drive available (which is independent of V+) and the β of this device.
When the maximum current limit is reached (approximately 16mA), the output transistor will come out of
saturation and the output voltage will rise very rapidly. The output saturation voltage is limited by the
approximately 60Ω rSAT of the output transistor. The low offset voltage of the output transistor (1.0 mV) allows the
output to clamp essentially to ground level for small load currents.
