Overview
The AD8648ARUZ-REEL is a quad, rail-to-rail input and output, single-supply operational amplifier manufactured by Analog Devices. It features a gain bandwidth product of 24 MHz and a slew rate of 11 V/μs. The device operates on a supply voltage range of 2.7 V to 5.5 V with 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 housed in a 14-lead TSSOP package.
Feature Summary
- Rail-to-rail input and output capability for wide dynamic range signal handling
- High-speed performance with 24 MHz bandwidth and 11 V/μs slew rate
- Low noise density of 8 nV/√Hz combined with very low input bias current
- Robust output drive supporting up to 120 mA short-circuit current
Applications
- Battery-powered instruments
- Multipole filters
- ADC front ends
- Barcode scanners
- Photodiode amplifiers
Procurement Notes
Verify the specific ordering suffix REEL against the manufacturer's official documentation to confirm the tape and reel packaging configuration. Ensure the component meets RoHS compliance requirements as indicated by the Z suffix in the base part number. Cross-reference the 14-lead TSSOP outline dimensions with your PCB footprint design to guarantee mechanical compatibility during assembly.
Selection Notes
Select this component when high-speed signal processing is required alongside low power consumption constraints. The rail-to-rail architecture makes it suitable for single-supply systems interfacing with CMOS ADCs or DACs. Consider the 2.7 V minimum supply voltage for battery-operated applications. Verify that the 1 pA input bias current meets the requirements for high-impedance sensor interfaces.
Part Context
This part belongs to the AD864x series of precision amplifiers from Analog Devices. The series includes dual-channel variants like the AD8646 and AD8647. The AD8648 specifically provides four independent amplifiers in a single package. This family is designed for portable instrumentation and audio applications requiring wide bandwidth and low distortion.
Replacement Considerations
The AD8648ARZ serves as a pin-compatible alternative using a 14-Lead SOIC_N package instead of TSSOP. The AD8646 and AD8647 are dual-channel versions within the same functional family.
