GENERAL DESCRIPTION
The ALD2332A/ALD2332B/ALD2332 is a monolithic high performance
dual precision voltage comparator built with advanced silicon gate
EPAD
tions. The ALD2332A/ALD2332B/ALD2332 offers ultra-low input offset
voltages and currents at its input pre-amplifier, precision voltage com-
parator and high-current output driver integrated on-chip, in one industry
standard pinout 8 Lead PDIP or SOIC package. Primary features include:
very high typical input impedance of 10 12 Ω; low input bias current of
10pA; fast response time of 520ns with only 10mV input step signal; very
low power dissipation of 175µA per comparator; single (+5V) or dual
(±5V) power supply operation; and 50mA push-pull output drivers.
The input voltage range includes ground, which makes these compara-
tors ideal for single supply low level signal detection with high source
impedance. The outputs can source and sink current allowing for
application flexibility. They can be used in either wired-OR connection
without pull-up resistor or push-pull configuration. ALD2332A/ALD2332B/
ALD2332 can also be used in wired-OR connection with other open
drain circuits such as the ALD2331/ALD2303 voltage comparators.
The ALD2332A/ALD2332B/ALD2332 voltage comparators are ideal for
a great variety of precision analog voltage comparator applications,
especially in low level signal detection circuits which require low standby
power and high output current.
