| INTEGRATED CIRCUITS NE527 Voltage comparator Product data Supersedes data of 1994 Aug 31 File under Integrated Circuits, IC11 Handbook 2001 Aug 03 Philips Semiconductors Philips Semiconductors Product data Voltage comparator NE527 DESCRIPTION The NE527 is a high-speed analog voltage comparator which, for the first time, mates state-of-the-art Schottky diode technology with the conventional linear process. This allows simultaneous fabrication of high speed TTL gates with a precision linear amplifier on a single monolithic chip. The NE527 is similar in design to the Philips Semiconductors NE529 voltage comparator except that it incorporates an "Emitter-Follower" input stage for extremely low input currents. This opens the door to a whole new range of applications for analog voltage comparators.

Response Time Test Circuit 2001 Aug 03 5 Philips Semiconductors Product data Voltage comparator NE527 APPLICATIONS One of the main features of the device is that supply voltages (V1+, V1-) need not be balanced, as in the following diagrams. For proper operation, however, negative supply (V1-) should always be at least 6 V more than the ground terminal (Pin 6). Input common-mode range should be limited to values of 2 V less than the supply voltages (V1+ and V1-) up to a maximum of 5 V as supply voltages are increased. It is also important to note that Output A is in phase with Input A and Output B is in phase with Input B.
