| a FEATURES Low Supply Current: 5.5 A max Single-Supply Operation: 2.2 V to 12 V Wide Bandwidth: 160 kHz Wide Input Voltage Range Rail-to-Rail Output Swing No Phase Reversal Output Short Circuit Current: 10 mA APPLICATIONS Portable Phones Comparator Battery Powered Instrumentation Safety Monitoring Remote Sensors Low Voltage Strain Gauge Amplifiers 5 A, Rail-to-Rail Output Operational Amplifier OP186 FUNCTIONAL BLOCK DIAGRAM 5-Lead SOT-23 (RT Suffix) OUT 1 V+ 2 5 V- OP186 TOP VIEW +IN 3 (Not to Scale) 4 -IN 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 (-40C to +125C) temperature range. The OP186 is available in the SOT-23-5 package.

ORDERING GUIDE Model OP186GRT Temperature Range -40C to +125C Package Description 5-Lead SOT-23 Package Option RT-5 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. WARNING!

Saturation Recovery Time 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. -10- REV. 0 OP186 SPICE MODEL * OP186 SPICE Macro-model Typical Values * 2/98, Ver. 1 * TAM / ADSC * * Copyright 1998 by Analog Devices * * Refer to "README.DOC" file for License State* ment.
