●Product Details
●The ADA4084-1 (single), ADA4084-2 (dual), and ADA4084-4 (quad) are single-supply, 10 MHz bandwidth amplifiers featuring rail-to-rail inputs and outputs. They are guaranteed to operate from +3 V to +30 V (or ±1.5 V to ±15 V).
●These amplifiers are well suited for single-supply applications requiring both ac and precision dc performance. The combination of wide bandwidth, low noise, and precision makes the ADA4084-1/ADA4084-2/ADA4084-4 useful in a wide variety of applications, including filters and instrumentation.
●Other applications for these amplifiers include portable telecommunications equipment, power supply control and protection, and use as amplifiers or buffers for transducers with wide output ranges. Sensors requiring a rail-to-rail input amplifier include Hall effect, piezoelectric, and resistive transducers.
●The ability to swing rail to rail at both the input and output enables designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios.
●The ADA4084-1/ADA4084-2/ADA4084-4 are specified over the industrial temperature range of −40°C to +125°C.
●The single ADA4084-1 is available in the 5-lead SOT-23 and 8-lead SOIC; the dual ADA4084-2 is available in the 8-lead SOIC, 8-lead MSOP, and 8-lead LFCSP surface-mount packages; and the ADA4084-4 is offered in the 14-lead TSSOP and 16-lead LFCSP.
●The ADA4084-1/ADA4084-2/ADA4084-4 are members of a growing series of high voltage, low noise op amps offered by Analog Devices, Inc.
