AD8663ACPZ-REEL7

Overview

The AD8663ACPZ-REEL7 is a single-channel, low noise, precision CMOS operational amplifier manufactured by Analog Devices. It features rail-to-rail output capability and utilizes DigiTrim technology for low offset voltage. The device operates on supply voltages ranging from 5 V to 16 V (single) or ±2.5 V to ±8 V (dual). Key electrical specifications include a maximum input offset voltage of 175 μV at 5 V supply, a typical input bias current of 0.3 pA, and a voltage noise density of 23 nV/√Hz at 1 kHz. The gain bandwidth product is 540 kHz with a slew rate of 0.3 V/μs at 16 V. It is housed in an 8-lead LFCSP package and supports an extended industrial temperature range of -40°C to +125°C.

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 as a unity-gain amplifier with low power consumption.

Applications

• Sensor front ends
• Transimpedance amplifiers
• Photodiode amplification
• Low power ADC drivers
• Medical diagnostic instruments

Procurement Notes

Verify that the component matches the specific AD8663ACPZ-REEL7 designation, which indicates the 8-lead LFCSP package variant. Confirm RoHS compliance status via the manufacturer's documentation. Ensure the ordering suffix corresponds to the reel packaging format required for surface-mount assembly processes.

Selection Notes

Select this component for designs requiring low noise and precision in single-supply environments up to 16 V. The low input bias current makes it appropriate for interfacing with high-impedance sources like photodiodes. Consider the 8-lead LFCSP package constraints regarding thermal dissipation and board space requirements compared to SOIC alternatives.

Part Context

This part belongs to the AD8663/AD8667/AD8669 family of low noise, precision, 16 V CMOS rail-to-rail operational amplifiers. While the AD8667 offers dual channels and the AD8669 provides quad channels, the AD8663 is configured as a single amplifier. All variants share similar electrical characteristics and utilize the same DigiTrim technology for precision performance.

Replacement Considerations

Direct functional substitutes within the same family include the AD8667ARZ and AD8669ARZ, though these differ in channel count. Verify pin compatibility and package dimensions when considering alternative packages such as the 8-lead SOIC (AD8663ARZ).
