AD8048ARZ-REEL7

Instrumentation, Op Amps, Buffer Amps Overview

The AD8048ARZ-REEL7 is a single-channel, general-purpose voltage feedback operational amplifier manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +85°C and is housed in an 8-lead SOIC package. The device is stable at gains of two or greater, featuring a small signal bandwidth of 260 MHz and a large signal bandwidth of 160 MHz (2 V p-p). Key electrical parameters include a typical slew rate of 1000 V/µs, settling time of 30 ns to 0.01% for a 2 V step, and input voltage noise density of 3.8 nV/√Hz. It supports supply voltages from ±3 V to ±6 V with a maximum quiescent current of 6.6 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific REEL7 suffix indicates reel packaging containing 750 units per reel, distinct from tube quantities. Confirm RoHS compliance status via official documentation. Ensure the operating environment remains within the specified -40°C to +85°C range. Validate that circuit configurations maintain a closed-loop gain of two or greater to ensure stability. Cross-reference the datasheet revision B specifications against procurement requirements.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a voltage feedback topology is required for stability at non-unity gains. The AD8048 offers superior large-signal bandwidth compared to the unity-gain stable AD8047. Consider its high slew rate and low noise profile for demanding signal processing tasks. Evaluate board layout constraints due to high-frequency sensitivity. Compare power consumption against system budget requirements given the 6.6 mA maximum supply current.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the AD8047/AD8048 family of high-speed, wide-bandwidth amplifiers designed to meet requirements previously served by current feedback designs. While the AD8047 is unity-gain stable, the AD8048 variant is optimized for gains of two or greater. Both devices combine the best characteristics of voltage and current feedback architectures, offering fast pulse response and low distortion in a standard 8-lead plastic package format.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8047ANZ serves as a functional substitute if unity-gain stability is required instead of gain-of-two stability. Verify pin compatibility and package dimensions before substitution. Note that bandwidth and slew rate specifications differ between the AD8047 and AD8048 variants.
