GENERAL DESCRIPTION
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
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.
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.
