AD8669ARUZ

Overview

The AD8669ARUZ is a quad, precision, low-noise 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. The device utilizes the DigiTrim® trimming technique to achieve low offset voltage and low input bias current. Key electrical parameters include a maximum offset voltage of 300 µV at 16 V, an input bias current of 0.3 pA, and a voltage noise density of 23 nV/√Hz. It offers a gain bandwidth product of 540 kHz and a slew rate of 0.3 V/µs. The component is housed in a 14-lead TSSOP package and supports an extended industrial operating temperature range from -40°C to +125°C.

Feature Summary

• Utilizes patented DigiTrim® trimming technology for high DC precision with low offset voltage.
• Features rail-to-rail outputs to maximize dynamic range when driving data converters.
• Provides very low input bias current suitable for high impedance sensor applications.
• Operates stably with unity-gain configurations across wide supply voltage ranges.

Applications

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

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm package type and RoHS compliance status. Confirm availability through authorized distributors as supply levels may vary. Ensure the selected variant matches the required pinout and thermal characteristics for the target PCB layout.

Selection Notes

Select this component for designs requiring multiple precision channels in a compact surface-mount footprint. Consider the 14-lead TSSOP package dimensions for board space constraints. Evaluate the trade-off between the 540 kHz bandwidth and the low power consumption profile relative to system requirements.

Part Context

This part belongs to the AD8663/AD8667/AD8669 family of low noise, precision, 16 V CMOS rail-to-rail operational amplifiers. While sharing core electrical specifications, the AD8669ARUZ specifically integrates four independent amplifier circuits within a single 14-lead TSSOP package, distinguishing it from the single-channel AD8663 and dual-channel AD8667 variants.

Replacement Considerations

Public confirmed substitute part numbers: AD8669ARZ (14-Lead SOIC_N).
