FUNCTIONAL BLOCK DIAGRAM
is a dual, rail-to-rail input, low power
comparator ideal for use in general-purpose applications. The
device operates from a single supply voltage of 2.3 V to 5.5 V
and draws a minimal amount of current. The quad
consumes only 22.1 µA of supply current. The low voltage and
low current operation of the
makes it ideal for
features a common-mode input voltage range
of 200 mV beyond rails, an offset voltage of 1 mV typical across
the full common-mode range, and a UVLO monitor. In addition,
the design of the comparator allows a defined output state upon
power-up. The comparator generates a logic low output if the
supply voltage is less than the UVLO threshold.
is available in a 8-lead, narrow body SOIC
is specified to operate over the
extended temperature range of −40°C to +125°C.
