GENERAL DESCRIPTION

The OP186 is a single, low voltage, ultralow power single­supply, 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.

NOTES

1

Stresses above those listed under Absolute Maximum Ratings may cause perma-

nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational sections
of this specification is not implied. Exposure to absolute maximum rating condi­tions for extended periods may affect device reliability.

2

For supplies less than ±5 V the differential input voltage is limited to the supplies.

CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection.
Although the OP186 features proprietary ESD protection circuitry, permanent damage may
occur on devices subjected to high energy electrostatic discharges. Therefore, proper ESD
precautions are recommended to avoid performance degradation or loss of functionality.

APPLICATIONS

The OP186 is very similar in design to the OP181. Please see the
OP181/OP281/OP481 data sheet for applications information.

Design of the OP186 was based on the OP181. The major dif­ference is that the trim structures have been removed. This
results in the offset of the OP186 being higher than the OP181.
There are no other major changes to the circuit. Other perfor­mance differences, such as the higher bandwidth and slightly
higher supply current, also result from the removal of the trim
resistors.
