AD8630ARUZ-REEL

Overview

The AD8630ARUZ-REEL is a quad zero-drift operational amplifier featuring rail-to-rail input and output capabilities. It operates on a single supply from 2.7 V to 5 V or dual supplies of ±1.35 V to ±2.5 V. Key electrical parameters include a typical offset voltage of 1 µV, maximum input bias current of 300 pA, and gain-bandwidth product of 2.5 MHz at 5 V. The device provides 130 dB CMRR and PSRR, with a slew rate of 1 V/µs. It consumes approximately 1.0 mA per amplifier and functions within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Utilizes patented auto-zeroing and chopping topology to eliminate 1/f noise and maintain ultralow offset drift over temperature.
• Features rail-to-rail input and output swings compatible with single-supply operation.
• Provides high precision with low offset voltage and minimal input bias current.
• Designed for fast overload recovery without requiring external components.

Applications

• Automotive sensors
• Pressure and position sensors
• Strain gage amplifiers
• Medical instrumentation
• Photodiode amplifiers

Procurement Notes

Verify the specific package variant against the datasheet ordering guide, as the ARUZ suffix denotes the TSSOP-14 package. Confirm that the REEL suffix matches the required tape and reel quantity for production integration. Ensure the component meets RoHS compliance requirements if applicable to the target assembly process.

Selection Notes

Select this component when system requirements demand high DC accuracy with minimal drift in harsh environments. The quad configuration allows multiple channels in a single package, reducing board space. Verify that the 2.5 MHz bandwidth and 1 V/µs slew rate are sufficient for the signal frequencies involved.

Part Context

This part belongs to the AD8628/AD8629/AD8630 family of zero-drift amplifiers. While the AD8628 is a single-channel device and the AD8629 is dual-channel, the AD8630 integrates four independent amplifiers. All share the same core architecture and electrical characteristics, differing primarily in channel count and package options.

Replacement Considerations

The AD8630ARZ-REEL serves as a pin-compatible alternative using the SOIC-14 package instead of TSSOP-14. Designers must verify thermal dissipation differences between the packages before substitution.
