AD8663ARZ-REEL

Overview

The AD8663ARZ-REEL is a single-channel, low noise, precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and utilizes DigiTrim trimming for low offset voltage. The device operates on single supplies from 5 V to 16 V or dual supplies of ±2.5 V to ±8 V. Key electrical characteristics include a maximum input offset voltage of 175 μV at 5 V supply, a typical gain bandwidth product of 520 kHz, and a maximum supply current of 275 μA per amplifier. It is housed in an 8-lead SOIC package.

Feature Summary

• Utilizes patented DigiTrim trimming technique to achieve low input offset voltage.
• Features rail-to-rail output stage providing increased dynamic range for driving data converters.
• Designed with CMOS architecture for low input bias current and low power consumption.
• Unity-gain stable operation suitable for direct feedback configurations.

Applications

• Sensor front ends
• Transimpedance amplifiers
• Electrometer applications
• Photodiode amplification
• Low power ADC drivers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm the packaging format. The REEL designation indicates tape and reel packaging intended for automated assembly processes. Ensure the component meets RoHS compliance requirements if mandated by the project specifications. Cross-reference the datasheet revision to confirm all electrical parameters align with the design requirements.

Selection Notes

Select this component when high precision and low noise are required in a single-supply environment. The wide supply voltage range accommodates various system architectures. Consider the thermal resistance values provided in the datasheet for heat dissipation planning. Evaluate the input bias current specifications for compatibility with high-impedance signal sources.

Part Context

This part belongs to the AD8663/AD8667/AD8669 family of precision amplifiers. While the AD8667 offers dual channels and the AD8669 provides quad channels, the AD8663 specifically contains a single operational amplifier channel. All members share similar electrical performance profiles but differ in pin counts and physical package options.

Replacement Considerations

Direct functional substitutes within the same family include the AD8667ARMZ for dual-channel applications and the AD8669ARZ for quad-channel implementations. Verify pinout compatibility before substitution. Other packages such as LFCSP or MSOP may be available depending on space constraints.
