Frequently asked questions
What is the difference between AD706ARZ and AD706AR-REEL?
Both parts are the same AD706 dual low-power bipolar op-amp die in an 8-lead SOIC package (R-8 suffix). The AD706ARZ is supplied in tube/tray packaging, while AD706AR-REEL is supplied on tape-and-reel for automated assembly. The "Z" suffix on AD706ARZ denotes RoHS-compliant lead finish per Analog Devices nomenclature; the AD706AR-REEL is the reeled variant of the same device.
Are AD706ARZ and AD706AR-REEL electrically and functionally identical?
Yes. Both are the AD706, a dual, low-power, unity-gain-stable bipolar operational amplifier with FET-like input characteristics. They share the same datasheet specifications, including typical input bias current of 50 pA, low offset voltage, and micropower supply current, since packaging format does not alter the silicon or electrical performance.
Can AD706ARZ and AD706AR-REEL be used interchangeably in a design?
Electrically, yes, because they are the same device. However, the physical delivery format differs: AD706ARZ is provided in tubes/trays and AD706AR-REEL on tape-and-reel. Interchangeability in production depends on whether the assembly line is set up for reeled or tube-fed placement; the PCB footprint and pinout are identical.
What package do AD706ARZ and AD706AR-REEL use?
Both devices are offered in an 8-lead SOIC (Small Outline Integrated Circuit) package, designated by the "R" suffix in the part number. The package is surface-mount and RoHS-compliant for the AD706ARZ variant.
What are the key specifications of the AD706?
The AD706 is a dual low-power bipolar op-amp featuring very low input bias current (typically 50 pA), low input offset voltage, unity-gain stability, and low supply current suitable for battery-powered and precision instrumentation applications. These specifications apply equally to AD706ARZ and AD706AR-REEL.
Why would a designer choose the reeled AD706AR-REEL over AD706ARZ?
The AD706AR-REEL tape-and-reel format is intended for high-volume automated pick-and-place assembly, reducing manual handling and enabling efficient SMT production. AD706ARZ in tubes/trays is typically used for prototyping, low-volume runs, or manual assembly.
Do AD706ARZ and AD706AR-REEL differ in moisture sensitivity or handling requirements?
Both are the same SOIC package and share the same moisture sensitivity level and handling requirements as defined by the manufacturer's datasheet and packaging information. The reel format of AD706AR-REEL is designed for automated handling, but the device-level MSL classification is identical.
