APPLICATIONS
Battery Powered Instrumentation Power Supply Control and Protection Telecom DAC Output Amplifier ADC Input Buffer 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.
