ADVANCED LINEAR DEVICES, INC. ALD4303A/ALD4303 QUAD PRECISION MICROPOWER CMOS VOLTAGE COMPARATOR WITH DRIVER GENERAL DESCRIPTION The ALD4303A/ALD4303 is a precision monolithic high performance quad voltage comparator with open drain output built with advanced silicon gate CMOS technology. It features very high typical input impedance of 1012 ; low input bias current of 10pA; very low power dissipation of 7.5A per comparator; micropower operation; high output drive and single (+5V) or dual (± 5V) power supply operation. FEATURES 3V, 5V and 12V supply Guaranteed to drive 200 loads Fanout of 30LS TTL loads Guaranteed maximum supply current of 22A per comparator Industry standard pinout of LM393 type Extremely low input bias currents -- 10pA Virtually eliminates source impedance effects Single (+5V) and dual supply (± 5V) operation CMOS, NMOS and TTL compatible Open drain wired-OR outputs Compatible with push-pull outputs High output sinking current -- 60mA Low supply current spikes High gain -- 100V/mV The input voltage range includes ground, making this comparator ideal for single supply low level signal detection with high source impedance. The ALD4303A/ALD4303 can be used in connection with other voltage comparator circuits such as the ALD2301/ALD2302/ALD4302 voltage comparators. The outputs can be connected to a higher external voltage than V+ and used in a wired-OR connection with other open drain circuits such as ALD2301/ALD2303. They can also be used with……
