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) and function with a single supply as low as 1.5 V.
These amplifiers are superb for single-supply applications
requiring both ac and precision dc performance. The combi-
nation 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 is
available in 8-lead SOIC surface mount packages. The dual 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.
