GENERAL DESCRIPTION

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).

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).

These amplifiers are well suited for single-supply applications

requiring both ac and precision dc performance. The combina-

tion of wide bandwidth, low noise, and precision makes the

ADA4084-2 useful in a wide variety of applications, including

filters and instrumentation.

For a more complete selection table of low input voltage noise

amplifiers, see the AN-940 Application Note, Low Noise

Amplifier Selection Guide for Optimal Noise Performance,

available at www.analog.com.

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.

¹Rail-to-rail output.

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.
