AD8652ARMZ

Overview

The AD8652ARMZ is a dual-channel, precision, low noise, and 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. The device features a gain-bandwidth product of 50 MHz at 5 V, a typical offset voltage of 100 μV specified over the entire common-mode range, and a slew rate of 41 V/μs. It exhibits a voltage noise density of 4.5 nV/√Hz and an input bias current of 1 pA. The amplifier supports rail-to-rail input and output swing and is available in an 8-lead MSOP package.

Feature Summary

• Features DigiTrim in-package trimming technology that measures and corrects offset voltage across the entire input common-mode range to minimize distortion.
• Provides true rail-to-rail input and output capability, maximizing usable voltage range for single-supply applications.
• Offers high-speed performance with a 50 MHz gain-bandwidth product and 41 V/μs slew rate suitable for fast signal processing.

Applications

• High speed ADCs and DACs
• Optical communications
• Broadband communications
• Cell phone PA control

Procurement Notes

Verify the specific ordering suffix 'ARMZ' corresponds to the 8-lead MSOP package configuration as defined in the manufacturer's official documentation. Confirm that the component meets RoHS compliance standards required for your assembly process. Ensure the operating temperature range of -40°C to +125°C aligns with your system's thermal design requirements before finalizing procurement.

Selection Notes

Select this component when designing circuits requiring high precision with minimal offset drift across varying common-mode voltages. The rail-to-rail input and output characteristics make it suitable for low-voltage single-supply systems where maximum dynamic range is critical. Consider its low noise profile for sensitive analog front-end applications.

Part Context

This part belongs to the AD865x family of amplifiers, which includes single (AD8651), dual (AD8652), and quad (AD8654) channel variants. All members share similar electrical characteristics, including the 50 MHz bandwidth and low noise specifications, but differ in channel count and pinout configurations to suit different packaging needs.

Replacement Considerations

The AD8651 serves as the single-channel equivalent within the same family. For direct replacement, verify that the existing circuit layout accommodates the dual-channel pinout of the AD8652 or if a single-channel variant like the AD8651 is sufficient for the application requirements.

FAQ

Does the AD8652 exhibit phase reversal?

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

How is the offset voltage managed in this device?

The 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.
