ADA4075-2ACPZ-RL

Overview

The ADA4075-2ACPZ-RL is a dual-channel, ultralow noise operational amplifier manufactured by Analog Devices Inc. It utilizes the iPolar process for high performance at lower power. Key specifications 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 operates on dual supplies ranging from ±4.5 V to ±18 V with a typical supply current of 1.8 mA per amplifier. It features a gain bandwidth product of 6.5 MHz, a slew rate of 12 V/μs, and an offset voltage maximum of 1 mV. The component is specified for operation within an extended industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify that the ordering suffix matches the required reel quantity and package variant. Confirm the specific revision level against the latest manufacturer documentation to ensure compatibility with design requirements. Check for any updates in the absolute maximum ratings or thermal resistance values before finalizing procurement plans.

Selection Notes

Select this component when ultralow noise is critical alongside moderate power constraints. The dual-supply architecture suits applications requiring symmetrical signal swings. Ensure the load capacitance remains within stability limits to prevent overshoot. Consider the 2 mm × 2 mm LFCSP package for high-density board layouts where space is limited.

Part Context

This part belongs to the ADA4075-2 family of ultralow noise amplifiers. It is designed using the iPolar advanced bipolar technology, which implements vertical junction isolation with lateral trench isolation. This manufacturing approach allows for smaller die sizes while maintaining fast speed and low power consumption compared to traditional bipolar processes.

Replacement Considerations

Consult official cross-reference data for verified substitutes. Verify pinout compatibility and electrical parameter equivalence before substitution.
