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).
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.
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.
