AD8047ARZ

Instrumentation, Op Amps, Buffer Amps Overview

The AD8047ARZ is a high-speed, general-purpose voltage feedback operational amplifier manufactured by Analog Devices Inc. It features a small signal bandwidth of 250 MHz and a large signal bandwidth of 130 MHz at unity gain. The device provides a typical slew rate of 750 V/µs and settles to within 0.01% in 30 ns for a 2 V step. It operates on supply voltages ranging from ±3 V to ±6 V with a typical quiescent current of 5.8 mA. The input voltage noise density is 5.2 nV/√Hz, and it can drive capacitive loads up to 50 pF.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'ARZ' corresponds to the 8-lead SOIC package variant rather than the PDIP option. Confirm RoHS compliance status as indicated by the 'Z' suffix in official documentation. Ensure the selected component meets the required industrial temperature range specifications for the intended operating environment before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when unity gain stability is required alongside high bandwidth performance typically found in current feedback amplifiers. Consider the AD8047 over the AD8048 if the circuit design necessitates operation at a closed-loop gain of one. Evaluate the trade-off between the lower noise current and the specific power consumption requirements of the system design.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8047/AD8048 family of wide bandwidth amplifiers designed to bridge the gap between traditional voltage feedback and current feedback topologies. The AD8047 specifically addresses applications requiring unity gain stability while maintaining high slew rates and wide bandwidths previously unattainable with standard voltage feedback designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8047ANZ serves as a direct pin-compatible replacement offering the same electrical characteristics but housed in an 8-Lead PDIP package instead of the SOIC format.
