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 system supplies (V_LOGIC+ and V_LOGIC-) to
make the output 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.

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.
