Frequently asked questions
What is the difference between the AD8602DRZ and the AD8602DR?
The AD8602DRZ and AD8602DR are both dual, precision, low-noise operational amplifiers from Analog Devices in an 8-lead SOIC package. The primary difference is the suffix: the "Z" designation in AD8602DRZ indicates RoHS-compliant, lead-free construction, while the AD8602DR is the non-RoHS (leaded) version. Electrical performance is otherwise identical per the datasheet.
Are the AD8602DRZ and AD8602DR electrically interchangeable?
Yes. Both parts share the same datasheet specifications, including supply voltage range of 2.7 V to 5.5 V, typical gain bandwidth of 8.4 MHz, low input offset voltage, and rail-to-rail input/output operation. The only documented difference is the RoHS/lead-free status of the package finish.
Can the AD8602DRZ be used as a drop-in replacement for the AD8602DR?
Yes, in most cases. Both are 8-lead SOIC devices with identical pinouts and electrical characteristics. The AD8602DRZ is the RoHS-compliant equivalent, so it can replace the AD8602DR where lead-free compliance is required, provided the PCB assembly process is compatible with the lead-free finish.
What package do the AD8602DRZ and AD8602DR use?
Both devices are supplied in an 8-lead SOIC (Small Outline Integrated Circuit) package, designated "R" in the ordering code. The package dimensions and pin configuration are the same for both variants.
What are the key specifications of the AD8602DRZ and AD8602DR?
Per the Analog Devices datasheet, both are dual rail-to-rail input/output op amps with a supply range of 2.7 V to 5.5 V, typical gain bandwidth of 8.4 MHz, low input offset voltage (typically 80 µV), low input bias current, and low noise. They are suited for precision signal conditioning, sensor interfaces, and portable instrumentation.
Does the "Z" suffix affect the operating temperature range or performance?
No. The "Z" suffix denotes RoHS compliance and lead-free packaging only. The operating temperature range and all electrical parameters are the same for the AD8602DRZ and AD8602DR as specified in the datasheet.
Which variant should be selected for a lead-free manufacturing process?
The AD8602DRZ should be selected for lead-free, RoHS-compliant manufacturing. The AD8602DR is the non-RoHS version and should only be used where leaded finish is acceptable or required by legacy processes.
