They are guaranteed to operate SOIC, 8-lead MSOP, and 8-lead LFCSP surface-mount from +3 V to +30 V (or 1.5 V to 15 V). 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 The ADA4084-1/ADA4084-2/ADA4084-4 are members of a of wide bandwidth, low noise, and precision makes the growing series of high voltage, low noise op amps offered by ADA4084-1/ADA4084-2/ADA4084-4 useful in a wide variety of Analog Devices, Inc. (see Table 1). applications, including filters and instrumentation. Table 1. Low Noise Op Amps Other applications for these amplifiers include portable telecom- Single Dual Quad Voltage Noise munications equipment, power supply control and protection, and AD8597 AD8599 1.1 nV/Hz use as amplifiers or buffers for transducers with wide output ADA4004-1 ADA4004-2 ADA4004-4 1.8 nV/Hz ranges. Sensors requiring a rail-to-rail input amplifier include AD8675 AD8676 2.8 nV/Hz rail-to-rail output Hall effect, piezoelectric, and resistive transducers. AD8671 AD8672 AD8674 2.8 nV/Hz OP27, OP37 3.2 nV/Hz The ability to swing rail to rail at both the input and output ADA4084-1 ADA4084-2 ADA4084-4 3.9 nV/Hz rail-to-rail enables designers to build multistage filters in single-supply input/output systems and to maintain high signal-to-noise ratios. The ADA4084-1/ADA4084-2/ADA4084-4 are specified over the industrial temperature range of 40C to +125C. Rev.
