AD8698ARZ-REEL7

Overview

The AD8698ARZ-REEL7 is a dual precision operational amplifier featuring rail-to-rail output capability. It offers a maximum offset voltage of 100 µV and drift below 2 µV/°C, eliminating manual trimming needs. Key electrical parameters include a gain bandwidth product of 1 MHz, slew rate of 0.4 V/µs, and input bias current of 700 pA max. It operates on supply voltages from ±2.5 V to ±15 V with a common-mode rejection ratio of 118 dB min. The device provides low noise performance at 8 nV/√Hz and functions within a temperature range of −40°C to +85°C.

Feature Summary

• Rail-to-rail output maximizes dynamic range in various applications
• High precision with low offset voltage and drift eliminates manual trimming
• Low input bias current minimizes errors with high impedance sensors
• Internal protection allows input overvoltage beyond supply rails

Applications

• Photodiode amplifiers
• Sensors and controls
• Multipole filters
• Integrators
• ADC input amplifiers

Procurement Notes

Verify the specific ordering suffix REEL7 corresponds to the SOIC-8 package configuration as listed in the official Analog Devices ordering guide. Confirm that the component meets the specified -40°C to +85°C operating temperature range for your application environment. Ensure compatibility with standard surface-mount assembly processes for the narrow 8-lead SOIC footprint.

Selection Notes

Select this component when high DC accuracy is required without external trimming due to its low offset voltage characteristics. It is suitable for applications driving capacitive loads directly, though compensation may be needed for loads exceeding 50 nF. Consider the 1 MHz bandwidth limit when designing active filters or signal conditioning circuits requiring higher frequency response.

Part Context

This part belongs to the AD8698 family of dual precision, rail-to-rail output operational amplifiers. The family includes variants in MSOP and SOIC packages. The AD8698ARZ-REEL7 specifically denotes the SOIC-8 package version supplied in tape and reel format. Other family members include single (AD8694) and quad (AD8696) configurations sharing similar electrical specifications.

Replacement Considerations

Direct substitutes within the same package and specification profile are not explicitly confirmed in the provided documentation. Verify pinout compatibility and electrical parameter equivalence before replacing with other dual op-amp models.
