微功耗,单电源,轨到轨输入/输出运算放大器 Micropower Single-Supply Rail-to-Rail Input/Output Op Amps
GENERAL DESCRIPTION
The OP191, OP291 and OP491 are single, dual and quad micropower, single-supply, 3 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. All are guaranteed to operate from a 3 volt single supply as well as ±5 volt dual supplies.
Fabricated on Analog Devices’ CBCMOS process, the OP191 family has a unique input stage that allows the input voltage to safely extend 10 volts beyond either supply without any phase inversion or latch-up. The output voltage swings to within millivolts of the supplies and continues to sink or source current all the way to the supplies.
Applications for these amplifiers include portable telecom equipment, power supply control and protection, and interface for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezo electric, and resistive transducers.
