HA-4900, HA-4902, HA-4905

Precision Quad Comparators

The HA-4900 series are monolithic, quad, precision

comparators offering fast response time, low offset voltage,

low offset current and virtually no channel-to-channel

crosstalk for applications requiring accurate, high speed,

signal level detection. These comparators can sense signals

at ground level while being operated from either a single +5V

supply (digital systems) or from dual supplies (analog

networks) up to

±15V. The HA-4900 series contains a unique

current driven output stage which can be connected to logic

levels directly compatible (no external components needed)

with any standard logic or special system logic levels. In

combination analog/digital systems, the design employed in

the HA-4900 series input and output stages prevents

troublesome ground coupling of signals between analog and

digital portions of the system.

These comparators’ combination of features make them

ideal components for signal detection and processing in data

acquisition systems, test equipment and

microprocessor/analog signal interface networks.

For military grade product, refer to the HA-4902/883 data

sheet.

NOTE: Intersil Pb-free plus anneal products employ special Pb-free

material sets; molding compounds/die attach materials and 100%

matte tin plate termination finish, which are RoHS compliant and

compatible with both SnPb and Pb-free soldering operations. Intersil

Pb-free products are MSL classified at Pb-free peak reflow

temperatures that meet or exceed the Pb-free requirements of

IPC/JEDEC J STD-020.
