FEATURES

Wide bandwidth: 4 MHz Low offset voltage: 65 μV Unity-gain stable High slew rate: 4.0 V/μs Low noise: 3.9 nV/√Hz

APPLICATIONS

Battery-powered instrumentation Power supply control and protection Telecommunications DAC output amplifier ADC input buffer GENERAL DESCRIPTION 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 V to 36 V (or ±1.5 V to ±18 V). These amplifiers are superb for single-supply applications requiring both ac and precision dc performance. The combination of wide 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- munications 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. The OP184/OP284/OP484 are specified over the hot extended industrial temperature range of −40°C to +125°C. The single OP184 is available in 8-lead SOIC surface mount packages. The dual OP284 is available in 8-lead PDIP and SOIC surface mount packages. The quad OP484 is available in 14-lead PDIP and 14-lead, narrow-body SOIC packages.
