Overview
The AD8646WARZ-RL is a dual-channel, precision operational amplifier manufactured by Analog Devices Inc. It features rail-to-rail input and output capabilities with a gain bandwidth product of 24 MHz and a slew rate of 11 V/µs. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V, drawing a maximum supply current of 2 mA per amplifier. Key electrical characteristics include a maximum offset voltage of 2.5 mV, an input bias current of 1 pA, and a short-circuit output current of ±120 mA. It is qualified for automotive applications under AEC-Q100 standards and housed in an 8-lead SOIC package.
Feature Summary
- Rail-to-rail input and output operation enables full signal swing across the entire supply range.
- Automotive qualification ensures reliability and compliance with industry standards.
- Low input bias current minimizes loading effects on high-impedance signal sources.
- High output drive capability supports low-impedance loads without performance degradation.
Applications
- Battery-powered instruments
- Multipole filters
- ADC front ends
- Sensors
- Barcode scanners
Procurement Notes
Verify that the component matches the specific automotive-grade designation indicated by the 'W' suffix. Confirm the package type corresponds to the 8-lead SOIC format. Ensure the revision level aligns with the required design specifications. Check for RoHS compliance status as documented in the manufacturer's ordering guide. Validate the operating temperature range against environmental requirements.
Selection Notes
Select this model when automotive qualification is mandatory for the application. Choose this part over non-automotive variants if long-term supply stability is critical. Consider the rail-to-rail feature for maximizing dynamic range in single-supply systems. Evaluate the 24 MHz bandwidth against the highest frequency signals present in the circuit design.
Part Context
This component belongs to the AD8646 family of precision amplifiers. It shares core electrical specifications with other members of the series but is distinguished by its automotive qualification. The 'W' suffix denotes compliance with automotive reliability standards. The 'RL' suffix indicates reel packaging for automated assembly processes.
Replacement Considerations
AD8646ARZ-REEL serves as a standard commercial alternative lacking automotive qualification. AD8646ARMZ offers the same electrical performance in an MSOP package. Verify pin compatibility and thermal characteristics before substituting.
