AD8663ARZ-REEL7

Overview

The AD8663ARZ-REEL7 is a single-channel, precision CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and operates on supply voltages ranging from 5 V to 16 V (single) or ±2.5 V to ±8 V (dual). The device utilizes DigiTrim® trimming technology to achieve low offset voltage of 175 μV maximum at 5 V and 300 μV maximum at 16 V. Key electrical characteristics include a low supply current of 275 μA maximum per amplifier, low input bias current of 300 fA typical, and low noise density of 23 nV/√Hz at 1 kHz. It is unity-gain stable with a gain bandwidth product of 520 kHz at 5 V and 540 kHz at 16 V. The component is specified over an extended industrial temperature range of −40°C to +125°C and is housed in an 8-lead narrow SOIC package.

Feature Summary

• Utilizes patented DigiTrim® trimming technique to achieve low offset voltage across the common-mode range.
• Features extremely low input bias current suitable for high impedance sensor applications.
• Provides rail-to-rail output swing to maximize dynamic range when driving data converters.
• Operates stably with supply voltages up to 16 V while maintaining low power consumption.

Applications

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

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the specific tape-and-reel packaging configuration required for automated assembly processes. Confirm that the RoHS compliant status indicated by the Z suffix meets environmental regulations for the target deployment region. Ensure the 8-lead SOIC_N package dimensions align with the printed circuit board footprint design constraints.

Selection Notes

Select this component for designs requiring precision amplification with minimal power draw in single-supply systems. The wide supply voltage range accommodates both 5 V and 16 V system architectures without modification. Consider the low input bias current when interfacing with high-impedance sources such as photodiodes or electrometer probes where leakage currents must be minimized.

Part Context

This part belongs to the AD866x family of low noise, precision, 16 V CMOS rail-to-rail operational amplifiers. The family includes dual-channel (AD8667) and quad-channel (AD8669) variants sharing identical core specifications. All members utilize the same DigiTrim® technology and are designed for applications typically associated with higher-priced JFET amplifiers.

Replacement Considerations

Direct functional equivalents within the same package include the AD8663ARZ and AD8663ARZ-REEL. For multi-channel requirements, the AD8667 series offers dual-channel performance with identical electrical characteristics.
