AD8652ARZ-REEL

Overview

The AD8652ARZ-REEL is a dual-channel precision operational amplifier from the Analog Devices AD865x family, housed in an 8-lead SOIC package. It operates on a single supply voltage ranging from 2.7 V to 5.5 V and features rail-to-rail input and output capabilities. The device offers a gain bandwidth product of 50 MHz and a slew rate of 41 V/μs. Key electrical characteristics include a typical offset voltage of 90 μV (maximum 300 μV) and a voltage noise density of 4.5 nV/√Hz at 100 kHz. Input bias current is specified as low as 1 pA, with a maximum of 600 pA across the extended industrial temperature range of −40°C to +125°C.

Feature Summary

• Utilizes DigiTrim technology for post-package trimming of offset voltage across the entire common-mode range.
• Features true rail-to-rail input and output architecture for maximizing usable voltage range.
• Provides high open-loop gain and maintains stability without phase reversal within power supply limits.

Applications

• Optical communications
• Laser source drivers and controllers
• Broadband communications systems
• High-speed ADC and DAC interfaces

Procurement Notes

Verify that the ordering suffix REEL corresponds to tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the specific revision level matches design requirements, as datasheet specifications may be subject to change. Ensure the selected package variant aligns with PCB footprint constraints for the 8-lead SOIC form factor.

Selection Notes

Select this component for applications requiring high speed combined with precision DC accuracy in low-voltage environments. The rail-to-rail input stage allows operation near ground potential, making it suitable for single-supply designs. Consider the 40 mA output drive capability for driving moderate loads while maintaining signal integrity.

Part Context

This part belongs to the AD865x family of low noise, low distortion CMOS amplifiers. The AD8652 specifically denotes the dual-channel configuration, whereas the AD8651 represents the single-channel version. Both variants share identical electrical performance characteristics and utilize the same pinout configurations for interchangeability in system design.

Replacement Considerations

The AD8651ARZ serves as the single-channel equivalent within the same family. Designers should verify that any substitute devices maintain compatibility with the 2.7 V to 5.5 V supply range and offer similar rail-to-rail input/output swing characteristics.

FAQ

Does the AD8652 exhibit phase reversal when input voltages exceed the supply rails?

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

How is the offset voltage managed in this device?

Offset voltage is managed using DigiTrim technology, which measures and corrects the offset after assembly to minimize variation caused by mechanical stresses.
