GENERAL DESCRIPTION  
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).  
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.  
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.  
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. (see Table 1).  
Table 1. Low Noise Op Amps  
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 ADA4084-1/ADA4084-2/ADA4084-4 are specified over  
the industrial temperature range of −40°C to +125°C.
