ADVANCED LINEAR ALD2302A/ALD2302 DEVICES, INC. DUAL PRECISION CMOS VOLTAGE COMPARATOR WITH PUSH-PULL DRIVER FEATURES GENERAL DESCRIPTION Guaranteed to drive 200 loads The ALD2302A/ALD2302 are monolithic precision high performance Fanout of 30LS TTL loads dual voltage comparators built with advanced silicon gate CMOS Low supply current of 175A each technology. The primary features are: very high typical input impedance 12 comparator of 10 low input bias current of 10pA fast response time of 180ns Pinout of LM193 type industry standard very low power dissipation of 175A per comparator and single (+5V) comparators or dual (5V) power supply operation. Extremely low input bias currents -- typically 10pA The input voltage range includes ground, which makes these compara- Virtually eliminates source impedance effects tors ideal for single supply low level signal detection with high source Low operating supply voltage of 4V to 10V impedance. The outputs can source and sink current allowing for Single (+5V) and dual supply (5V) operation application flexibility. They can be used in either wired-OR connection High speed for both large and small signals without pull-up resistor or push-pull configuration. The ALD2302A/ -- 180ns for TTL inputs and 400ns for 20mV ALD2302 can also be used in wired-OR connection with other open overdrive drain circuits such as the ALD2301/ALD2303 voltage comparators. CMOS, NMOS and TTL compatible Push-pull outputs-current sourcing/ sinking The ALD2302A/ALD2302 voltage comparators are ideal for a great High output sinking current -- typically 60mA variety of applications, especially in low level signal detection circuits Low supply current spikes which require low standby power and high output current. For quad High gain -- 100V/mV packages, use the ALD4302A/ALD4302 quad voltage comparator.
