ADVANCED ALD2301A/ALD2301B LINEAR ALD2301C/ALD2301 DEVICES, INC. DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH OPEN DRAIN DRIVER GENERAL DESCRIPTION FEATURES The ALD2301A/ALD2301B/ALD2301C/ALD2301 is a monolithic high Fanout of 30LS TTL loads performance dual voltage comparator built with advanced silicon gate Low supply current of 110A typical CMOS technology. It features very high typical input impedance of Functional equivalent to LM193 industry 12 10 low input bias current of 10pA fast response time of 300ns standard comparators very low power dissipation of 55A per comparator and single (+5V) Extremely low input bias currents or dual (5V) power supply operation. -- typically 10pA Virtually eliminates source impedance The input voltage range includes ground, making this comparator effects ideal for low level signal detection with high source impedance. The Low operating supply voltage of 3V to 10V outputs are open-drain configuration, allowing maximum application Single (+5V) and dual supply (5V) operation flexibility, such as wired-OR connection. The outputs can be con- High speed for both large signal and low + nected to a higher external voltage than V . level signals -- 300ns typical for TTL inputs CMOS, NMOS and TTL compatible The ALD2301A/ALD2301B/ALD2301C/ALD2301 is ideal for a great Wired-OR open drain outputs variety of voltage comparator applications, especially low level signal High output sinking current -- typically 60mA detection circuits requiring low standby power, yet retaining high Low supply current spikes output current capability as needed.
