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 (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-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.
