OP284ESZ-REEL

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 are can used 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. Applications includes battery-powered instrumentation, power supply control and protection, telecommunications, DAC output amplifier, ADC input buffer.
