ADA4075-2ARZ-RL

Overview

The ADA4075-2ARZ-RL is a dual-channel, ultralow noise operational amplifier manufactured by Analog Devices Inc. It utilizes the iPolar process to achieve high performance with low power consumption. Key electrical parameters include a typical voltage noise density of 2.8 nV/√Hz at 1 kHz and a total harmonic distortion plus noise of 0.0002%. The device features a gain bandwidth product of 6.5 MHz and a slew rate of 12 V/μs. It operates on dual supplies ranging from ±4.5 V to ±18 V, drawing 1.8 mA per amplifier. The input offset voltage is typically 0.2 mV, with a maximum of 1 mV. It is specified for an extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify that the ordering suffix -RL corresponds to the tape and reel packaging format required for automated assembly processes. Confirm the specific package variant matches the design footprint, as the ADA4075-2 family includes both SOIC and LFCSP options. Ensure the component revision aligns with the latest datasheet specifications for thermal and electrical characteristics before finalizing procurement orders.

Selection Notes

Select this component when ultralow noise and low distortion are critical requirements alongside moderate power consumption. It is appropriate for applications requiring high slew rates and wide bandwidths in dual-supply environments. Consider the available packages based on board space constraints, noting that the LFCSP offers a smaller footprint compared to the standard SOIC option while maintaining similar electrical performance.

Part Context

The ADA4075-2 belongs to Analog Devices' lineup of low noise precision operational amplifiers. It is designed using the iPolar process, which combines vertical junction isolation with lateral trench isolation. This technology enables lower noise performance in smaller die sizes with faster speeds and reduced power usage compared to traditional bipolar technologies. The device is part of a broader series including single and quad channel variants.

Replacement Considerations

Check for availability of the non-reel version (ADA4075-2ARZ) if bulk quantities or tube packaging are preferred. Verify pin compatibility if substituting with other dual-channel low noise amplifiers from the same manufacturer family.
