AD8664ARZ-REEL

Overview

The AD8664ARZ-REEL is a quad precision CMOS operational amplifier manufactured by Analog Devices. It features a gain-bandwidth product of 4 MHz and a slew rate of 3.5 V/µs. The device operates on a single supply voltage ranging from 5 V to 16 V, with a maximum supply voltage of 16 V. Key electrical specifications include an input offset voltage of 50 µV, an input bias current of 1 pA, and an input voltage noise density of 12 nV/√Hz. Common-mode rejection ratio (CMRR) and power-supply rejection ratio (PSRR) are both rated at 110 dB. The quiescent current per channel is approximately 1.55 mA, totaling 6.2 mA for the quad package. The output is rail-to-rail, and it is housed in a 14-lead SOIC package.

Feature Summary

• Utilizes DigiTrim® trimming technology to achieve low offset voltage characteristics without requiring external adjustments.
• Provides rail-to-rail output capability, maximizing dynamic range in single-supply applications.
• Combines low input bias current with low noise, suitable for high-impedance sensor interfaces.

Applications

• Photodiode amplification circuits
• Battery-powered instrumentation systems
• High-performance ADC and DAC drivers

Procurement Notes

Verify the specific suffix REEL7 against the datasheet to confirm tape-and-reel packaging quantities and orientation. Ensure the operating temperature range matches the application requirements, as industrial variants may differ from extended versions. Cross-reference the manufacturer part number with official Analog Devices documentation to avoid counterfeit components.

Selection Notes

Select this component when multiple precision amplifiers are required in a compact footprint. Compare input bias current and offset voltage against JFET alternatives for cost-sensitive designs. Verify that the 4 MHz bandwidth meets the signal frequency requirements of the target application.

Part Context

This part belongs to the AD8661/AD8662/AD8664 family of precision amplifiers. The AD8664 variant specifically integrates four independent channels within a single 14-lead package. It shares core architectural features with the single-channel AD8661 and dual-channel AD8662, including the use of CMOS technology for low power consumption and high input impedance.

Replacement Considerations

Direct functional substitutes within the same family include AD8661ARZ (single channel) and AD8662ARZ (dual channel). For pin-compatible replacements, verify if other quad precision amplifiers from Analog Devices or competitors meet the 50 µV offset and 1 pA bias current specifications.
