• Single or Dual Voltage Supply Operation
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.
Applications
• Threshold Detector
• Zero Crossing Detector
• Window Detector
These comparators’ combination of features make them
ideal components for signal detection and processing in data
acquisition systems, test equipment and
• Analog Interfaces for Microprocessors
• High Stability Oscillators
• Logic System Interfaces
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.
