OP284ESZ vs OP284ESZ-REEL7 vs OP284FSZ Comparison

The OP284ESZ is a dual Operational Amplifier with rail-to-rail input/output. This amplifier is superb for single supply applications requiring both AC and precision DC performance. The combination of bandwidth, low noise and precision makes the OP284 useful in a wide variety of applications, including filters and instrumentation. Other applications for this amplifier includes portable telecom equipment, power supply control and protection and as amplifiers or buffers for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include hall effect, piezo electric 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.

Product Details The OP184/OP284/OP484 are single, dual and quad single-supply, 4 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. They are guaranteed to operate from +3 to +36 (or ±1.5 to ±18) volts and will function with a single supply as low as +1.5 volts. These amplifiers are superb for single supply applications requiring both ac and precision dc performance. The combination of bandwidth, low noise and precision makes the OP184/OP284/ OP484 useful in a wide variety of applications, including filters and instrumentation. Other applications for these amplifiers include portable telecom equipment, power supply control and protection, and as amplifiers or buffers for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezo electric, 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. The OP184/OP284/OP484 are specified over the HOT extended industrial (-40°C to +125°C) temperature range. The single and dual are available in 8-pin plastic DIP plus SO surface mount packages. The quad OP484 is available in 14-pin plastic DIPs and 14-lead narrow-body SO packages. ### Features and Benefits
