Overview
The AD8651ARMZ-REEL is a single-channel, precision, low-noise CMOS operational amplifier manufactured by Analog Devices. It features rail-to-rail input and output capabilities with 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 characteristics 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 is housed in an 8-lead MSOP package.
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 maximum dynamic range.
- Provides high open-loop gain and excellent common-mode rejection ratio (CMRR) stability.
Applications
- Optical communications
- Laser source drivers and controllers
- Broadband communications
- High-speed ADCs and DACs
- Video line drivers
Procurement Notes
Verify that the ordering suffix matches the required packaging format. Confirm the specific part number variant against the manufacturer's official documentation to ensure correct pinout and thermal specifications. Cross-reference the datasheet revision to validate performance parameters before finalizing procurement decisions.
Selection Notes
Select this component for applications requiring high speed combined with precision DC accuracy. The rail-to-rail I/O capability makes it suitable for low-voltage single-supply systems. Consider the 50 MHz bandwidth and 41 V/µs slew rate for signal processing requirements where fast settling times are critical.
Part Context
This component belongs to the AD865x family of amplifiers, which includes dual-channel variants like the AD8652. The family is characterized by its use of CMOS technology to achieve low power consumption while maintaining high performance metrics such as low noise and high bandwidth within compact surface-mount packages.
Replacement Considerations
The AD8652 serves as the dual-channel counterpart within the same family. Verify pin compatibility and channel count requirements when considering alternative single-channel precision amplifiers from other manufacturers.
FAQ
Does the AD8651 exhibit phase reversal?
No, the AD8651 does not exhibit phase reversal for common-mode voltages within the power supply range.
What is the input protection mechanism?
The inputs are protected with ESD diodes to either power supply, capable of withstanding up to 4000 V ESD events without degradation.
