Overview
The AD8648WARUZ is a quad, rail-to-rail input and output operational amplifier designed for single-supply operation between 2.7 V and 5.5 V. It features a gain bandwidth product of 24 MHz and a slew rate of 11 V/μs. The device offers low offset voltage (maximum 2.5 mV) and low noise density of 8 nV/√Hz. It provides high output drive capability with short-circuit current up to 120 mA. Qualified for automotive applications, it operates within a temperature range of -40°C to +125°C in a 14-lead TSSOP package.
Feature Summary
- Rail-to-rail input and output capability enables full signal swing in single-supply systems.
- High output drive capability supports low impedance loads and audio line driving.
- Automotive qualification ensures reliability for demanding vehicle environments.
- Low input bias current and low noise support precision sensor interfacing.
Applications
- Battery-powered instruments
- Multipole filters
- ADC front ends
- Barcode scanners
- Photodiode amplifiers
Procurement Notes
Verify the specific 'W' suffix indicates automotive qualification when sourcing this component. Confirm the 14-lead TSSOP package dimensions match your PCB footprint requirements. Ensure supply voltage constraints remain within the specified 2.7 V to 5.5 V range during integration. Check for RoHS compliance status if required by your manufacturing standards.
Selection Notes
Select this part for applications requiring high-speed signal processing with wide dynamic range. The quad configuration reduces board space compared to individual dual or single amplifiers. Consider the 120 mA output current for driving heavy loads directly. Verify that the 24 MHz bandwidth meets your AC performance needs without excessive power consumption.
Part Context
This component belongs to the AD864x family of precision amplifiers from Analog Devices. It shares core electrical characteristics with the AD8646 (dual) and AD8647 (dual with shutdown). The primary distinction lies in the channel count and specific packaging options tailored for different volume and thermal requirements.
Replacement Considerations
The AD8648ARUZ serves as the standard commercial version of this component. Both share identical electrical specifications and pinouts. The 'W' suffix specifically denotes automotive qualification, which may be critical for replacement in vehicle electronics.
