AD8663ACPZ-REEL

Overview

The AD8663ACPZ-REEL7 is a single-channel, precision, low-noise CMOS operational amplifier manufactured by Analog Devices. It features rail-to-rail output capability and utilizes patented DigiTrim® technology to achieve 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 specifications include a maximum supply current of 285 μA per amplifier, a gain bandwidth product of 540 kHz, and a slew rate of 0.3 V/μs at 16 V. It maintains an input bias current as low as 0.3 pA and offers a voltage noise density of 23 nV/√Hz at 1 kHz.

• 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 the package type matches the LFCSP-8 footprint dimensions provided in the datasheet outline drawings. Ensure the component meets RoHS compliance standards indicated by the Z suffix in the base part number before finalizing procurement orders.

Selection Notes

Select this component for designs requiring high DC precision combined with low power consumption in extended industrial temperature ranges. The wide supply voltage range supports compatibility with various system architectures. Consider the low input bias current when interfacing with high-impedance sources to minimize signal errors. Verify that the 540 kHz bandwidth meets the AC performance requirements of the target application.

Part Context

This component belongs to the AD8663/AD8667/AD8669 family of low noise, precision, 16 V CMOS rail-to-rail operational amplifiers. The AD8663 variant specifically provides a single amplifier channel, whereas other family members offer dual or quad configurations. All variants share similar electrical characteristics and utilize the same DigiTrim® technology for precision offset management.

Replacement Considerations

The AD8663ARZ serves as a direct pin-compatible alternative packaged in an 8-Lead SOIC_N format. Both parts share identical electrical specifications and functionality but differ in physical package dimensions and thermal resistance characteristics.

FAQ
