LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS AZ339

Data Sheet

General Description

The AZ339 series consists of four independent preci-

sion voltage comp arators with an offset voltage speci-

fication as low as 2mV. The input common mode

voltage range of these comparators includes ground,

even when operated from a single power supply volt-

age. Operation from split power supplies is also possi-

ble and the low power supply current drain is

independent of the magnitude of the power supply

voltage.

The AZ339 series is designed to directly interface with

TTL and CMOS.

The AZ339 series can be widely used in such applica-

tions as battery charger, cordless telephone, switching

power supply, DC-DC module and PC motherboard.

The AZ339 series are available in 2 Packages: DIP-14

and SOIC-14.

Note 1: Stresses greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the

device. These are stress ratings only, and functional operation of the device at these or any other conditions

beyond those indicated un der "Recommended Operating Co nditions" is not implied. Exposure to "Absolute Max-

imum Ratings" for extended peri ods may affect device reliability.

Note 2: 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 vo ltages of the comparators to go to the V+ voltag e 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 volt age, which was negative, again returns to a value greater than -0.3 VDC

(at 25oC).

Note 3: At output switch poi nt, VO=1.4V, RS=0 with V CC from 5V to 15V, and over the full common-mode range

(0V to VCC-1.5V), at 25oC.

Note 4: The direction of the inp ut current is out of the PNP input st age. This current is essentially const ant, inde-

pendent of the state of the output, so no loading charge exists on the reference of input lines.

Note 5: The input common-mode voltage of either input signal voltage should not be allowed to go negative by

more than 0.3V. The upper end of the common-mode volt age range is VCC-1.5V, but either or both inputs can go

to +18V without damage, independent of the m agnitude of VCC.

Note 6: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns

can be obtained.
