AD8677ARZ-REEL7

Overview

The AD8677ARZ-REEL7 is a precision, ultralow offset operational amplifier manufactured by Analog Devices Inc. It utilizes iPolar technology to deliver high accuracy in an 8-lead narrow SOIC 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 typical supply current of 1.1 mA per amplifier, 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 compact surface-mount footprint.
• Provides enhanced common-mode rejection ratio and power supply rejection ratio compared to standard industry amplifiers.
• Maintains stability of offsets and gain virtually regardless of variations in time or temperature.
• Offers low noise performance with minimal peak-to-peak voltage noise in the 0.1 Hz to 10 Hz frequency band.

Applications

• Medical and industrial instrumentation
• Sensor and control systems including thermocouples and RTDs
• Strain bridge measurements
• Shunt current measurements
• Precision filters

Procurement Notes

Verify that the ordering suffix REEL7 corresponds to the specific tape and reel packaging configuration required for automated assembly processes. Confirm the RoHS compliance status indicated by the Z suffix aligns with environmental regulations applicable to the manufacturing region. Ensure the component matches the 8-lead narrow SOIC physical dimensions specified in the datasheet outline drawings before finalizing procurement orders.

Selection Notes

Select this component when circuit design requires high DC precision combined with low power consumption in a small form factor. The device serves as a direct functional replacement for OP07-type amplifiers where improved thermal stability and lower bias currents are necessary. Consider the 0.6 MHz gain bandwidth product and 0.2 V/µs slew rate to ensure adequate dynamic performance for the intended signal frequencies.

Part Context

The AD8677 series represents a next-generation evolution of precision amplifiers built on Analog Devices' iPolar process technology. This architecture allows for superior performance metrics within smaller packages compared to legacy bipolar designs. The AD8677ARZ-REEL7 variant specifically denotes the single-channel version housed in an 8-lead narrow SOIC package, optimized for applications demanding high accuracy without excessive board space utilization.

Replacement Considerations

The datasheet identifies the AD8677 as a successor to the OP07 type amplifier. Designers upgrading existing circuits should verify pin compatibility and ensure that the improved input bias current and offset drift characteristics do not require adjustments to external nulling or feedback networks previously designed for older generation devices.
