ALD2302集成电路（IC）的比较器规格书PDF中文资料

GENERAL DESCRIPTION

The ALD2302A/ALD2302 are monolithic precision high performance dual voltage comparators built with advanced silicon gate CMOS technology. The primary features are: very high typical input impedance of 1012Ω; low input bias current of 10pA; fast response time of 180ns; very low power dissipation of 175µA per comparator; and single (+5V) or dual (±5V) power supply operation.

FEATURES

• Fanout of 30LS TTL loads

• Low supply current of 175µA each comparator

• Pinout of LM193 type industry standard comparators

• Extremely low input bias currents -- 10pA

• Virtually eliminates source impedance effects

• Low operating supply voltage of 4V to 12V

• Single (+5V) and dual supply (±5V) operation

• High speed for both large and small signals -- 180ns for TTL inputs and 400ns for 20mV overdrive
