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 requiring 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, DAC output amplifier, and ADC input buffer.
The document describes the OP184, OP284, and OP484 as precision rail-to-rail input and output operational amplifiers. These devices are designed for single-supply operation with a wide bandwidth of 4 MHz and low offset voltage, making them suitable for battery-powered instrumentation, telecom equipment, and power supply control applications.
