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 to +36 (or
as +1.5 volts.
These amplifiers are superb for single supply applications re-
quiring 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 amplifi-
ers 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 en-
ables designers to build multistage filters in single-supply sys-
tems 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.
