AD8651ARZ-REEL

Overview

The AD8651ARZ-REEL is a single-channel, precision CMOS operational amplifier manufactured by Analog Devices. It features a gain bandwidth product of 50 MHz and a slew rate of 41 V/µs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V. Key electrical specifications include a typical input offset voltage of 100 µV, an input bias current of 1 pA, and a voltage noise density of 4.5 nV/√Hz at 100 kHz. It provides rail-to-rail input and output swing capabilities.

Feature Summary

• Utilizes DigiTrim in-package trimming technology to correct offset voltage across the entire common-mode range.
• Features true rail-to-rail architecture allowing input and output signals to extend to both positive and negative supply rails.
• Employs parallel NMOS and PMOS differential pairs to maintain high common-mode rejection ratio during transition regions.

Applications

• Optical communications
• Laser source drivers/controllers
• Broadband communications
• High speed ADCs and DACs
• Video line drivers

Procurement Notes

Verify that the component matches the specific REEL packaging format indicated in the model number. Confirm the manufacturer is Analog Devices Inc. Ensure the part meets RoHS compliance requirements for your manufacturing process. Check datasheet revision history for any updates to absolute maximum ratings or thermal resistance values before finalizing procurement.

Selection Notes

Select this component when high-speed signal processing requires low distortion and low noise characteristics. It is suitable for applications demanding precise amplification with minimal offset drift over temperature. Consider the extended industrial temperature range and single-supply operation constraints. Evaluate the need for rail-to-rail performance in low-voltage environments.

FAQ

Does the AD8651 exhibit phase reversal?

No, the AD8651 does not exhibit phase reversal for common-mode voltages within the power supply range.

How is the offset voltage calibrated?

The offset voltage is calibrated using DigiTrim technology, which measures and corrects the offset after assembly to account for mechanical stresses.
