GENERAL DESCRIPTION
The OP186 is a single, low voltage, ultralow power single-
supply, amplifier featuring rail-to-rail outputs. Specifications are
guaranteed at +2.2 V, +2.7 V, and +5.0 V single supply as well
as ± 5 V dual supplies.
Fabricated on Analog Device’s CBCMOS process, the OP186
features a bipolar input and an output that swings to within
millivolts of the supplies while continuing to sink or source
current all the way to the supplies.
Applications for these amplifiers include safety monitoring,
portable equipment, battery and power supply control, and as
signal conditioning and interface for transducers in very low
power systems.
The output’s ability to swing rail-to-rail and not increase supply
current when the output is driven to a supply enables the
OP186 to be used as a comparator in very low power systems.
The OP186 is specified over the extended industrial (–40°C to
+125°C) temperature range. The OP186 is available in the
SOT-23-5 package.
