GENERAL D ESCRIP TIO N
T he OP184/OP184/OP284/OP484 are single, dual and quad
single-supply, 4 MHz bandwidth amplifiers featuring rail-to-rail
inputs and outputs. T hey 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.

T hese amplifiers are superb for single supply applications re-
quiring both ac and precision dc performance. T he 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.

T he 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 maintain high signal-to-noise ratios.
