AD8039AR

Instrumentation, Op Amps, Buffer Amps Overview

The AD8039AR is a dual-channel, low-power, 350 MHz voltage feedback amplifier manufactured by Analog Devices Inc. It operates on a supply voltage range of 3 V to 12 V with a typical quiescent current of 1 mA per amplifier. The device features a 425 V/μs slew rate and an input offset voltage maximum of 3 mV. Noise performance includes 8 nV/√Hz voltage noise and 600 fA/√Hz current noise at 100 kHz. It provides -90 dB SFDR at 1 MHz and supports capacitive loads up to 20 pF without external components.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package type (SOIC-8) and temperature rating (-40°C to +85°C) against project requirements. Confirm that the dual-channel configuration matches the design needs, as the single-channel AD8038 variant offers different pinouts and disable features. Ensure proper bypassing and grounding techniques are applied during PCB layout to maintain high-frequency stability.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when both high bandwidth and low power consumption are critical constraints. The dual-channel architecture saves board space compared to using two single amplifiers. Consider the AD8038 if a disable feature or single-channel configuration is required instead. Evaluate the capacitive load drive capability, as larger loads may require series resistors to prevent overshoot.

Instrumentation, Op Amps, Buffer Amps Part Context

The AD8039 is part of the AD8038/AD8039 family of low-power, high-speed voltage feedback amplifiers. Manufactured using Analog Devices' proprietary XFCB process, these devices balance speed and power efficiency. The AD8039 specifically provides two independent channels in compact packages like SOIC-8 and SOT-23, making it suitable for dense circuit designs.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The AD8038 serves as the single-channel counterpart within the same family. Verify pinout compatibility if substituting between single and dual versions, as they differ significantly. No other direct cross-references are documented in the provided datasheet.
