Overview: HA-4902/883
Precision Quad Comparator 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.
