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

±1.5 to ±18) volts and will function with a single supply as low

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.
