GENERAL DESCRIPTION
The ALD4302 is a monolithic high performance quad voltage comparator
built with advanced silicon gate CMOS technology. It features very high
typical input impedance of 1012
; low input bias current of 10pA; fast
response time of 120ns; very low power dissipation of 150
A per compara-
tor; and single +5V or dual
±5V power supply operation.
The input voltage range includes ground, making this comparator ideal for
single supply low level signal detection with high source impedance. The
outputs can source and sink current, allowing application flexibility, and can
be used in either wired-OR connection without pull up resistor or push-pull
configuration. The ALD4302 can be used in wired-OR connection with
other open drain circuits such as the ALD2301 and ALD2303 voltage
comparators.
The ALD4302 is ideal for a great variety of precision voltage comparator
applications, especially low level signal detection circuits requiring low
standby power, yet retaining high output current capability.
