OP284EPZ

OP284 is a dual, single-supply 4MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. It is guaranteed to operate from 3V to 36V (or ±1.5V to ±18V). This amplifier is superb for single-supply applications requiring both AC and precision DC performance. The combination of wide bandwidth, low noise and precision makes the OP284 useful in a wide variety of applications, including filters and instrumentation. Other applications for these amplifiers include portable telecommunications equipment, power supply control and protection and use as amplifiers or buffers for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include hall effect, piezoelectric and resistive transducers. The ability to swing rail-to-rail at both the input and output enables designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios.
