AD8662ARZ-REEL

Overview

The AD8662ARZ-REEL is a dual precision CMOS operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail output capability and operates within a supply voltage range of 5 V to 16 V. Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 3.5 V/µs, an input offset voltage of 50 µV, and an input bias current of 300 pA. The device delivers a channel output current of 140 mA with a common-mode rejection ratio of 100 dB and an input voltage noise density of 12 nV/√Hz. It is housed in an SOIC-8 package and supports surface mount installation across an operating temperature range of -40°C to +125°C.

Feature Summary

• Utilizes DigiTrim® patented trimming technology for low offset voltage characteristics
• Provides rail-to-rail output swing for maximum dynamic range
• Features low input bias current suitable for high impedance sensor interfaces

Applications

• Photodiode amplification circuits
• Battery-powered instrumentation systems
• High-performance analog-to-digital converter (ADC) drivers

Procurement Notes

Verify the specific REEL suffix against the manufacturer's official documentation to confirm tape-and-reel packaging specifications. Ensure the SOIC-8 pinout matches the target PCB footprint design. Cross-reference the RoHS compliance status with current regulatory requirements before integration into production assemblies.

Selection Notes

Select this component when dual-channel precision amplification with rail-to-rail output is required. The 4 MHz bandwidth and low noise density make it suitable for signal conditioning tasks. Compare the 300 pA input bias current against other series variants if ultra-low leakage is critical for the specific application environment.

Part Context

This part belongs to the AD8661/AD8662/AD8664 family of low-noise, precision CMOS operational amplifiers. The AD8662 variant specifically provides two independent channels within a single compact package. It shares core architectural features with the single-channel AD8661 and quad-channel AD8664 models, offering consistent performance metrics across the series.

Replacement Considerations

The AD8662ARMZ serves as a functional equivalent in MSOP-8 packaging. Verify pin compatibility and thermal characteristics when substituting between SOIC and MSOP form factors.
