AD8048AN

Instrumentation, Op Amps, Buffer Amps Overview

The AD8048AN is a high-speed, 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 PDIP package. The device features a typical supply current of 5.8 mA and supports dual supply voltages from ±3 V to ±6 V. Key electrical specifications include a small-signal bandwidth of 260 MHz at a gain of +2, a large-signal bandwidth of 160 MHz (2 V p-p), and a slew rate of 1000 V/µs. It exhibits low input voltage noise of 3.8 nV/√Hz and can drive capacitive loads up to 50 pF.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'AN' against the manufacturer's official Ordering Guide to confirm the package type and packing quantity. Ensure the component meets RoHS compliance requirements if specified by the project constraints. Cross-reference the datasheet revision to confirm that electrical characteristics match the intended design parameters before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a voltage feedback topology is required with stability at non-unity gains. It serves as a suitable alternative to current feedback amplifiers where balanced high-impedance inputs are necessary. Consider its wide bandwidth and low noise profile for applications requiring precise signal conditioning at high frequencies.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8048AN belongs to the AD8047/AD8048 family of wide bandwidth amplifiers designed to combine the best characteristics of both current and voltage feedback architectures. While the AD8047 variant is unity gain stable, the AD8048 is optimized for gains of two or greater, offering enhanced performance metrics such as higher slew rates and larger signal bandwidths compared to its counterpart.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8047AN is a related part within the same family but differs in stability requirements, being unity gain stable rather than stable at gains of two or greater. Verify circuit compatibility regarding feedback resistor values and gain configurations when substituting between these variants.
