Precision Quad Comparator
HA-4902/883 Features The HA-4902/883 is a monolithic, quad, precision comparator
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. This comparator 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 В±15V.
The HA-4902/883 contains a unique current driven output
stage which can be connected to logic system supplies
(VLOGIC+ and VLOGIC -) 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-4902/883 input and output stages prevents troublesome
ground coupling of signals between analog and digital portions
of the system. This circuit is processed in accordance to MIL-STD-883 and
is fully conformant under the provisions of Paragraph 1.2.1 This comparators’ combination of features make it an ideal
component for signal detection and processing in data
acquisition systems, test equipment and
microprocessor/analog signal interface networks. Pin Configuration
