AD8047AN

Instrumentation, Op Amps, Buffer Amps Overview

The AD8047ANZ is a single-channel, unity-gain stable voltage feedback operational amplifier from Analog Devices. It features a small-signal bandwidth of 250 MHz and a large-signal bandwidth of 130 MHz at 2 V p-p. The device offers a typical slew rate of 750 V/µs and settles to 0.01% within 30 ns for a 2 V step. Input voltage noise density is 5.2 nV/√Hz, with a quiescent supply current of 6.6 mA maximum. It operates on dual supplies ranging from ±3 V to ±6 V and is housed in an 8-lead PDIP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'ANZ' corresponds to the 8-lead PDIP package and industrial temperature range (-40°C to +85°C). Confirm RoHS compliance status as indicated by the 'Z' suffix in official documentation. Ensure the component matches the Rev. B datasheet specifications for dynamic performance and DC characteristics before integration into high-frequency designs.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the AD8047ANZ when unity gain stability is required alongside high bandwidth and low distortion. Compare against the AD8048 if higher gain stability (G >= 2) or faster slew rates are needed. Consider the voltage feedback architecture for active filter flexibility compared to current feedback alternatives. Evaluate power supply bypassing requirements due to the high-speed nature of the device.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8047 is part of the AD8047/AD8048 family of very high-speed, wide-bandwidth amplifiers. These devices utilize a proprietary circuit design that combines characteristics of both current feedback and voltage feedback architectures. They are designed to meet requirements previously dependent on current feedback amplifiers while offering the flexibility of voltage feedback inputs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8048 is the companion device in the same family, differing primarily in stability requirements and slew rate. Verify pin compatibility and package dimensions when substituting. No other direct public substitute part numbers are confirmed in the provided documentation.
