ADA4084-2:  30V Low Noise, Low Power RRIO Dual Op Amp

Product Details

Product Status:Recommended for New Designs

The ADA4084-2 is a dual, single-supply, 10 MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. It is guaran-teed 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 ADA4084-2 useful in a wide variety of applications, including filters and instrumentation.

Other applications for these amplifiers include portable telecom-munications 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 ADA4084-2 is specified over the industrial temperature range of −40°C to +125°C. The dual ADA4084-2 is available in the 8-lead SOIC, MSOP, and LFCSP surface-mount packages.

The ADA4084-2 is a member of a growing series of high voltage, low noise op amps offered by Analog Devices, Inc., (see Table 1).
