Analog Devices Inc. ADA4084-1/-2/-4 Low Power Operational Amplifiers

Analog Devices ADA4084 product line is comprised of ADA4084-1 (single), ADA4084-2 (dual), and ADA4084-4 (quad), 30V 10MHz bandwidth amplifiers with rail-to-rail inputs and outputs. Guaranteed to operate from +3V to +30V, ADA4084-1/-2/-4 are well-suited for single-supply applications requiring both AC and precision DC performance. With a combination of wide bandwidth, low noise, and precision, ADA4084-1/-2/-4 amplifiers are useful in a wide variety of applications including filters and instrumentation.

Specified to perform over the industrial temperature range of −40°C to +125°C, these amplifiers are also used in portable telecommunications equipment, power supply control, and protection. They are also used as amplifiers or buffers for transducers with wide output ranges. With the capability to swing rail to rail at both the input and output, the ADA4084-1/-2/-4 amplifiers enable designers to build multistage filters in single-supply systems and to maintain high signal-to-noise ratios.
