ADVANCED LINEAR ALD2303A/ALD2303 DEVICES, INC. DUAL PRECISION MICROPOWER CMOS VOLTAGE COMPARATOR WITH DRIVER FEATURES GENERAL DESCRIPTION The ALD2303A/ALD2303 is a precision monolithic high performance 3V, 5V, and 10V supply dual voltage comparator built with advanced silicon gate CMOS Guaranteed to drive 200 loads 12 technology. It features very high typical input impedance of 10 Fanout of 30LS TTL loads low input bias current of 10pA very low power dissipation of 7.5A per Guaranteed maximum supply current of comparator and single (+5V) or dual (5V) power supply operation. 20A for each comparator Pinout of LM193 type industry standard The input voltage range includes ground, making this comparator comparators ideal for single supply low level signal detection with high source Extremely low input bias currents impedance. The ALD2303A/ALD2303 can be used in connection with -- typically 10pA other voltage comparator circuits such as the ALD2301/ALD2302/ Virtually eliminates source impedance ALD4302 voltage comparators. The output can be connected to a effects + higher external voltage than V . Single (+5V) and dual supply (5V) operation CMOS, NMOS and TTL compatible The ALD2303A/ALD2303 is ideal for high precision micropower volt- Open drain wired-OR outputs age comparator applications, especially low level signal detection High output sinking current -- typically 60mA circuits requiring low standby power, yet retaining high output current Low supply current spikes capability.
