Aerospace Quad Low Noise, Rail-to-Rail I/O, Low Power Operational Amplifiers

The ADA4084-4S (quad) is a single-supply, 10 MHz bandwidth amplifier featuring rail-to-rail inputs and outputs. It is guaranteed to operate from +3 V to +30 V (or ±1.5 V to ±15 V).

This amplifier is well suited for single-supply applications requiring both ac and precision dc performance. The combination of wide bandwidth, low noise, and precision makes the ADA4084-4S useful in a wide variety of applications, including filters and instrumentation.

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 represents the latest generation of the OP484S generation amplifiers.

The ADA4084-4S is specified over the military temperature range of −55°C to +125°C. The quad ADA4084-4S is available in the 14-lead flat pack surface-mount package.

The ADA4084-4S is a member of a growing series of high voltage, low noise op amps offered by Analog Devices, Inc.
