Overview: HA-4900, HA-4902, HA-4905
Data Sheet September 1998 File Number 2855.3 Precision Quad parators
The HA-4900 series are monolithic, quad, precision parators 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 parators 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 (VLOGIC+ and VLOGIC-) to make the output levels directly patible (no external ponents needed) with any standard logic or special system logic levels. In bination 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.
