GENERAL DESCRIPTION
The ALD2331A/ALD2331B/ALD2331 is a monolithic high performance
dual precision voltage comparator built with advanced silicon gate EPAD
CMOS technology intended for high precision analog applications. The
ALD2331A/ALD2331B/ALD2331 offers ultra-low input offset voltages
and currents at its input pre-amplifier, precision voltage comparator 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 1012; low input bias current of 10pA; fast
response time of 750ns with only 10mV input step signal; very low power
dissipation of 55A per comparator; and single (+5V) or dual (±5V) power
supply operation; and 50mA open drain output drivers.
The input voltage range includes ground, making this comparator ideal for
low level signal detection with high source impedance. The outputs are
open-drain configurations, allowing maximum application flexibility, such as
wired-OR connection and various different output loads. An external pull-
up resistor is required for each output, although the value of the pull-up
resistor can vary over a wide range in order to suit the application needs.
The outputs can be connected to a higher external voltage than V+.
The ALD2331A/ALD2331B/ALD2331 is ideal for a great variety of precison
analog voltage comparator applications, especially low level signal detec-
tion circuits requiring low standby power, yet retaining high output current
capability as needed.
