ADA4084-4ACPZ-RL

Overview

The ADA4084-4ACPZ-RL is a quad, low noise, rail-to-rail input/output operational amplifier from Analog Devices. It operates on single supplies from +3 V to +30 V or dual supplies of ±1.5 V to ±15 V. Key electrical characteristics include a typical gain bandwidth product of 15.9 MHz and a unity-gain crossover frequency of 9.9 MHz. The device features a typical supply current of 0.625 mA per amplifier at ±15 V and a voltage noise density of 3.9 nV/√Hz at 1 kHz. It is specified over an industrial temperature range of −40°C to +125°C.

Procurement Notes

Verify the specific package type and ordering suffix against the manufacturer's official documentation to ensure compatibility with design requirements. Confirm that the component meets all necessary environmental and safety standards required for the intended application before procurement.

Selection Notes

Select this component for applications requiring multiple channels with rail-to-rail performance and low power consumption. Ensure the supply voltage range and operating temperature limits align with the system specifications. Consider the thermal resistance characteristics when designing the PCB layout for heat dissipation.

Part Context

This part belongs to the ADA4084 series, which includes single (ADA4084-1), dual (ADA4084-2), and quad (ADA4084-4) variants. The series is designed for high-voltage, low-noise applications. The quad version integrates four independent amplifiers in a single package, offering space savings for multi-channel designs.

Replacement Considerations

Direct replacements within the same family include the ADA4084-1 and ADA4084-2 for single and dual channel needs respectively. Other low-noise op-amps from Analog Devices may be considered if pinout and electrical specifications match the design requirements.
