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