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.
