AD8652ARMZ-REEL

Overview

The AD8652ARMZ-REEL is a dual-channel, precision, low noise, low distortion CMOS operational amplifier manufactured by Analog Devices Inc. It operates from a single supply voltage ranging from 2.7 V to 5.5 V and features rail-to-rail input and output swing capabilities. The device utilizes DigiTrim technology for post-package offset trimming across the entire common-mode range. Key electrical specifications include a gain bandwidth product of 50 MHz at 5 V, a typical slew rate of 41 V/μs, and a voltage noise density of 4.5 nV/√Hz. The part is housed in an 8-lead MSOP package and is rated for operation within an extended industrial temperature range of -40°C to +125°C.

Feature Summary

• Features rail-to-rail input and output swing capability for maximum dynamic range in single-supply applications.
• Incorporates DigiTrim technology to measure and correct offset voltage over the entire input common-mode range.
• Provides high-speed performance with a 50 MHz gain bandwidth product and 41 V/μs slew rate.
• Delivers low noise characteristics with a voltage noise density of 4.5 nV/√Hz.

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as REEL indicates tape-and-reel delivery. Confirm the specific variant (AD8652) corresponds to the dual-channel requirement rather than the single-channel AD8651. Ensure the component meets RoHS compliance standards if applicable to your manufacturing process. Cross-reference the datasheet revision to confirm all electrical parameters align with your design specifications before finalizing procurement.

Selection Notes

Select this component when a dual-channel configuration is required alongside high-speed signal processing needs. The AD8652 offers identical electrical performance to the AD8651 but integrates two amplifiers in one package. Consider the space-saving MSOP footprint for dense PCB layouts. Verify that the 40 mA output current drive capability meets the load requirements of your specific application circuit.

Part Context

This component belongs to the AD865x family of precision CMOS amplifiers from Analog Devices. The family includes the single-channel AD8651 and the dual-channel AD8652. Both variants share the same core architecture, utilizing iCMOS technology and DigiTrim trimming. They are designed for applications requiring high precision, low distortion, and wide bandwidth in low-voltage single-supply environments.

Replacement Considerations

The AD8651ARZ-REEL serves as the single-channel equivalent within the same family. For dual-channel replacements, verify pin compatibility with other 8-lead MSOP op-amps, though direct substitutes require matching electrical specs such as 50 MHz GBP and rail-to-rail I/O.

FAQ

Does the AD8652 exhibit phase reversal?

No, the AD8652 does not exhibit phase reversal for common-mode voltages within the power supply range.

What is the input bias current specification?

The input bias current is typically 1 pA at 25°C, increasing to a maximum of 600 pA over the extended industrial temperature range.

How is the offset voltage managed?

Offset voltage is managed using DigiTrim technology, which trims the amplifier after assembly to correct for mechanical stresses and ensures precision across the entire common-mode range.
