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.
