Comparator Quad 16-Pin CDIP

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 ±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 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.
