APPLICATIONS

Battery-powered instrumentation

High-side and low-side sensing

Power supply control and protection

Telecommunications

Digital-to-analog converter (DAC) output amplifiers

Analog-to-digital converter (ADC) input buffers

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, and ADA4084-4 useful in a wide

variety of applications, including filters and instrumentation.

The ADA4084-1, ADA4084-2, and 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, and ADA4084-4 are specified

over the industrial temperature range of −40°C to +125°C.
