AD8677ARZ

Overview

The AD8677ARZ is a precision operational amplifier manufactured by Analog Devices Inc. It features a maximum offset voltage of 130 μV and an input offset drift of 1.5 μV/°C. The device operates with a supply current of 1.1 mA and supports a wide supply voltage range from ±4 V to ±18 V. Key performance metrics include a gain bandwidth product of 0.6 MHz, a slew rate of 0.2 V/μs, and a minimum common-mode rejection ratio of 115 dB. It is housed in an 8-lead SOIC package and functions within an extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes iPolar process technology for enhanced accuracy and lower power consumption compared to standard OP07-type amplifiers.
• Provides high gain, CMRR, and PSRR specifications to maintain stability against time and temperature variations.
• Offers wider output swing and higher common-mode rejection ratio while maintaining excellent linearity at high closed-loop gains.

Applications

• Medical and industrial instrumentation
• Sensors and controls
• Thermocouple signal conditioning
• RTD measurements
• Strain bridges

Procurement Notes

Verify the specific ordering suffix to confirm the package type and reel configuration. Ensure the component matches the required RoHS compliance status indicated by the Z suffix. Confirm that the selected variant aligns with the necessary operating temperature range and pinout requirements for the target circuit design before finalizing procurement.

Selection Notes

Select this component when ultralow offset voltage and low drift are critical for DC precision applications. Consider the AD8677ARZ for designs requiring high CMRR and PSRR in a compact surface-mount footprint. Evaluate the trade-off between the 0.6 MHz bandwidth and the low noise characteristics relative to system speed requirements.

Part Context

The AD8677 series represents the next generation of precision amplifiers, building upon the legacy of the OP07. It integrates improved performance metrics such as lower input bias current and higher CMRR into smaller packages like the TSOT and SOIC. This evolution allows for enhanced accuracy in a reduced physical footprint suitable for modern electronic systems.

Replacement Considerations

The AD8677 is designed as a direct successor to industry-standard OP07-type amplifiers. Verify pin compatibility and electrical parameter alignment when substituting legacy parts. No other specific substitute part numbers are documented in the provided source material.
