BCD AS339AM-E1 Low power low offset voltage quad comparator Datasheet

Data Sheet
LOW POWER LOW OFFSET VOLTAGE QUAD COMPARATORS
General Description
Features
The AS339/339A consist of four independent precision voltage comparators with a typical offset voltage
of 2.0mV and high gain. They are specifically
designed to operate from a single power supply over
wide range of voltages. Operation from split power
supply is also possible and the low power supply current drain is independent of the magnitude of the
power supply voltage.
·
·
·
·
·
·
The AS339/339A series are compatible with industry
standard 339. AS339A has more stringent input offset
voltage than AS339.
·
·
·
The AS339 is available in DIP-14, SOIC-14 and
TSSOP-14 packages, AS339A is available in SOIC-14
package.

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 Maximum
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 VDC
(at 25oC).

Note 3: Limits over the full temperature are guaranteed by design, but not tested in production.
Note 4: The input common-mode voltage of either input signal voltage should not be allowed to go negatively by more than
0.3V (at 25oC). The upper end of the common-mode voltage range is VCC-1.5V (at 25oC), but either or both inputs can go to
+36V without damages, independent of the magnitude of the VCC.
