LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS
AZ339
General Description
Features
The AZ339 series consists of four independent preci-
sion voltage comparators 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.
·
Wide Supply Voltage Range
- Single Supply: 2.0V to 18V
- Dual Supplies: ±1.0V to ± 9V
Very Low Supply Current Drain: 0.8mA
·
- Independent of Supply Voltage
·
·
·
·
Low Input Bias Current: 25nA (Typical)
Low Input Offset Current: ±5nA (Typical)
Low Input Offset Voltage: ±2mV (Typical)
Input Common Mode Voltage Range Includes
Ground
The AZ339 series is designed to directly interface with
TTL and CMOS.
·
Differential Input Voltage Range Equals to the
Power Supply Voltage
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.
·
·
Low Output Saturation Voltage: 250mV at 4mA
Open Collector Output
Applications
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 under "Recommended Operating Conditions" is not implied. Exposure to "Absolute Max-
imum Ratings" for extended periods 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 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 was negative, again returns to a value greater than -0.3 V

Note 4: The direction of the input current is out of the PNP input stage. This current is essentially constant, 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 voltage range is V -1.5V, but either or both inputs can go
CC
to +18V without damage, independent of the magnitude of V
.
CC
Note 6: The response time specified is a 100mV input step with 5mV overdrive. For large overdrive signals 300ns
can be obtained.
