LOW POWER LOW OFFSET VOLTAGE DUAL

COMPARATORS

Features

General Description

The AP393 consists of two independent precision voltage

comparators with an offset voltage specification as low as 2.0

mV 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.

•

Wide supply

- Voltage range: 2.0V to 36V

- Single or dual supplies: ±1.0V to ±18V

Very low supply current drain (0.4 mA) – independent

of supply voltage

Low input biasing current: 25 nA

Low input offset current: ±5 nA

Maximum offset voltage: ±3 mV

•

Input common-mode voltage range includes ground

Differential input voltage range equal to the power

supply voltage

Application areas include limit comparators, simple analog to

digital converters; pulse, squarewave and time delay 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 power drain is a distinct advantage

over standard comparators.

•

Low output saturation voltage: 250 mV at 4 mA

Output voltage compatible with TTL, DTL, ECL, MOS

and CMOS logic systems

Packages: 8-pin SOP-8L and DFN (Under

Development) Green packages

LOW POWER LOW OFFSET VOLTAGE DUAL

COMPARATORS

Note 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 AP393 must be derated based on a 150°C maximum junction temperature. The low bias dissipation and the “ON-OFF”

characteristic of the outputs keeps the chip dissipation very small (P_D<100 mW), provided the output transistors are allowed

to saturate.

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 20 mA independent of the magnitude of V⁺.

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 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.

Note 5: The AP393 temperature specifications are limited to 0°C < T_A< +70°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 reference or input lines.

Note 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⁺.

Note 8: The response time specified is for a 100 mV input step with 5 mV overdrive. For larger overdrive signals 300 ns can be

obtained, see typical performance characteristics section.

Note 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).

Note 10: At output switch point, V_O~ 1.4V, R_S=0Ω with V⁺from 5V to 30V; and over the full input common-mode range (0V to V⁺-1.5V),

at 25°C.

Note 11: Refer to RETS193AX for AP393 military specifications.

Application Information

The AP393 are high gain, wide bandwidth devices which, 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.

prevent the input voltages from going negative more than -0.3

V_DC(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

which is 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

which 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 r_SATof 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.

The bias network of the AP393 establishes a drain current which

is independent of the magnitude of the power supply voltage

over the range of from 2.0 V_DCto 30 V_DC. 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 8). Protection should be provided to
