30 V, Low Noise, Rail-to-Rail I/O, Low Power Operational Quad Amplifer
The 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).
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 ADA4084-2 and ADA4084-4 useful in a wide variety of applications, including filters and instrumentation.
Other applications for these amplifiers include portable telecommunications 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 and ADA4084-4 are 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, and the ADA4084-4 is offered in the 14-lead TSSOP and 14-lead LFCSP.
The ADA4084-2 and ADA4084-4 are members of a growing series of high voltage, low noise op amps offered by Analog Devices, Inc.
