Overview
The AD8544ARZ-REEL is a quad CMOS rail-to-rail general-purpose operational amplifier manufactured by Analog Devices Inc. It operates on a single supply voltage ranging from 2.7 V to 5.5 V with a typical supply current of 45 µA per amplifier. The device features a gain bandwidth product of 1 MHz, an input bias current as low as 4 pA, and unity gain stability. It supports full output swing and includes AEC-Q100 qualification for automotive applications.
Feature Summary
- Rail-to-rail input and output capabilities enable maximum dynamic range in single-supply systems.
- Low power consumption of 45 µA per amplifier extends battery life in portable designs.
- High input impedance with extremely low bias currents suitable for high source impedance sensors.
Applications
- ASIC input or output buffering
- Photodiode amplifiers
- Piezoelectric transducer signal conditioning
- Medical instrumentation
Procurement Notes
Verify the specific package marking code RU-14 matches the required footprint. Confirm that the REEL suffix indicates tape and reel packaging rather than tube. Ensure the Z suffix confirms RoHS compliance status for your manufacturing process requirements.
Selection Notes
Select this component when four independent amplifiers are needed within a single package. Consider the 1 MHz bandwidth and 45 µA current draw for low-power active filter designs. Verify that the 4 pA input bias current meets the leakage requirements of your specific sensor interface circuitry.
Part Context
This part belongs to the AD854x family, which includes single (AD8541) and dual (AD8542) variants. All members share identical electrical characteristics but differ in channel count and package options. The AD8544 specifically provides four channels in a 14-lead narrow SOIC or TSSOP configuration.
Replacement Considerations
Direct functional equivalents include AD8544ARUZ and AD8544ARZ. For automotive grade requirements, consider the AD8544WARZ series. Single-channel replacements are available as AD8541ARTZ-REEL.
