AD8677AUJZ-R2

Overview

The AD8677AUJZ-R2 is a precision, ultralow offset operational amplifier manufactured by Analog Devices Inc. It utilizes the iPolar™ process to deliver high accuracy in a compact 5-lead TSOT package. Key electrical specifications include a maximum input offset voltage of 130 μV at +25°C and 350 μV across the extended temperature range of −40°C to +125°C. The device features a low supply current of 1.1 mA typical, a gain bandwidth product of 0.6 MHz, and a slew rate of 0.2 V/μs. It supports wide supply voltage operation from ±4 V to ±18 V.

Feature Summary

• Integrates ultralow offset voltage and drift characteristics within a small footprint using iPolar™ technology.
• Provides high common-mode rejection ratio (CMRR) and power supply rejection ratio (PSRR) for signal integrity.
• Maintains stability of offsets and gain virtually regardless of variations in time or temperature.
• Offers excellent linearity and gain accuracy 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 R2 corresponds to the reel packaging option when sourcing components. Confirm RoHS compliance status as indicated by the Z suffix in the base model number. Ensure the supplier provides documentation matching the Rev. A datasheet specifications for the AD8677 series. Cross-reference the manufacturer part number with authorized distribution channels to guarantee authenticity and traceability.

Selection Notes

Select this component for applications requiring precision amplification in space-constrained designs. The 5-lead TSOT package offers a smaller footprint compared to standard SOIC options while maintaining similar electrical performance. Consider the 1.1 mA supply current for low-power systems. Evaluate the 0.6 MHz gain bandwidth product against required signal frequencies to ensure adequate phase margin and stability.

Part Context

The AD8677 represents a next-generation evolution of precision amplifiers, building upon the performance legacy of industry-standard OP07 types. Manufactured using Analog Devices' proprietary iPolar™ process, it achieves enhanced accuracy and lower power consumption. This family includes variants in both 5-lead TSOT and 8-lead narrow SOIC packages, catering to diverse board layout requirements.

Replacement Considerations

Direct functional replacements may include other ultralow offset amplifiers from Analog Devices such as the AD8676 or AD8672, though pinouts and specific parameters like offset voltage and bandwidth differ. Verify compatibility with existing circuit designs when substituting.
