AD8662ARZ

Overview

The AD8662ARZ 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 specifications include a gain-bandwidth product of 4 MHz, a slew rate of 3.5 V/µs, and an input offset voltage of 50 µV. The device draws 1.25 mA of operating current per channel and provides an output current of 140 mA. It exhibits low input bias current (300 pA), high common-mode rejection ratio (100 dB), and power supply rejection ratio (115 dB). The component is housed in an 8-lead SOIC package and supports operation temperatures from -40°C to +125°C.

Feature Summary

• Dual-channel precision CMOS architecture with rail-to-rail output swing
• Low input offset voltage and bias current for high accuracy applications
• High common-mode and power supply rejection ratios

Applications

• Precision signal conditioning circuits
• Data acquisition systems requiring high accuracy
• Industrial process control instrumentation

Procurement Notes

Verify the specific suffix 'ARZ' to confirm the SOIC-8 package and lead-free RoHS compliance status. Confirm availability as distribution channels may indicate limited stock or restricted sales regions. Ensure the ordering part number matches the required package type and temperature grade before finalizing procurement orders.

Selection Notes

Select this component when dual-channel precision amplification with rail-to-rail output is required. Compare against single-channel variants like AD8661 if only one amplifier is needed. Consider the AD8662ARMZ for MSOP-8 packaging requirements. Verify that the 4 MHz bandwidth and 3.5 V/µs slew rate meet the dynamic performance needs of the target application.

Part Context

The AD8662ARZ belongs to the AD866x series of precision amplifiers from Analog Devices. This family includes single-channel (AD8661) and quad-channel (AD8668) variants sharing similar electrical characteristics. The 'ARZ' designation specifically identifies the dual-channel version in the standard 8-lead SOIC surface-mount package.

Replacement Considerations

The AD8662ARMZ serves as a pin-compatible alternative offering the same electrical performance in an MSOP-8 package.
