Replacement verdict
Compatible functional replacement candidate
The AD8062ARMZ-R7 and AD8062ARM are functionally equivalent dual operational amplifiers from Analog Devices, sharing the same core die, package footprint, and electrical specifications. The only distinction is the RoHS-compliant Z-grade molding compound in the -R7 variant, making it a direct drop-in substitute for the non-RoHS AD8062ARM in new designs.

Key electrical and mechanical differences between the two devices
| Parameter | AD8062ARMZ-R7 | AD8062ARM | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op-amps, so the feedback topology and compensation behavior are equivalent for substitution. |
| Number of Channels | 2 | 2 | Dual-channel configuration must match to preserve board layout and signal path count. |
| Gain Bandwidth Product | 300 MHz | 300 MHz | GBW determines the maximum usable frequency for a given closed-loop gain; identical values ensure equivalent AC performance. |
| Slew Rate | 650 V/µs | 650 V/µs | Slew rate limits large-signal bandwidth and distortion; matching values preserve transient response. |
| Input Offset Voltage (Max) | 1 mV | 1 mV | Offset voltage affects DC accuracy; identical limits ensure the same precision in DC-coupled applications. |
| Supply Voltage Range | 2.7 V to 24 V | 2.7 V to 24 V | The supply range must match to ensure compatibility with the existing power rail design. |
| Supply Current per Channel | 6.5 mA | 6.5 mA | Quiescent current impacts power budget and thermal design; matching values keep power consumption unchanged. |
| Input Bias Current | 3.5 µA | 3.5 µA | Bias current affects DC error in high-impedance circuits; identical values preserve accuracy. |
| Package / Mounting | 8-MSOP, Surface Mount | 8-MSOP, Surface Mount | Package and mounting must match for physical drop-in compatibility on the PCB. |
| Packaging / Ordering Format | Tape & Reel (R7) | Tube / Tray | The R7 suffix denotes tape-and-reel packaging for automated assembly, while the base part is supplied in bulk; this affects manufacturing handling but not electrical function. |

Frequently asked questions
What is the difference between AD8062ARMZ-R7 and AD8062ARM?
Both are dual, low-power, high-speed operational amplifiers from Analog Devices in an 8-lead MSOP package. The AD8062ARMZ-R7 is the RoHS-compliant (Z) version supplied in 7-inch tape-and-reel packaging (R7), while AD8062ARM is the non-RoHS version. The electrical die and performance specifications are the same; the differences are package/ordering suffix and compliance status.
Are AD8062ARMZ-R7 and AD8062ARM electrically identical?
Yes. Both variants share the same AD8062 die and datasheet specifications, including 300 MHz -3 dB bandwidth, 650 V/µs slew rate, 6.8 nV/√Hz input voltage noise, and 6.4 mA/amplifier supply current. The suffix differences relate to RoHS compliance and packaging format, not to electrical performance.
Can AD8062ARM be used as a drop-in replacement for AD8062ARMZ-R7?
Functionally and pinout-wise, yes, since both use the same 8-lead MSOP package and pin configuration. However, AD8062ARM is not RoHS-compliant, so substitution may violate RoHS compliance requirements in regulated markets. Verify your compliance obligations before substituting.
What does the "Z" suffix mean in AD8062ARMZ-R7?
The "Z" suffix in Analog Devices part numbering denotes RoHS compliance (lead-free, RoHS-compliant construction). AD8062ARMZ-R7 is therefore the RoHS-compliant variant, whereas AD8062ARM lacks this designation.
What does the "R7" suffix indicate on AD8062ARMZ-R7?
The "R7" suffix indicates tape-and-reel packaging, specifically a 7-inch reel. This is a packaging/ordering designation and does not affect the electrical characteristics of the device.
What are the key specifications of the AD8062?
The AD8062 is a dual voltage-feedback operational amplifier with 300 MHz -3 dB bandwidth, 650 V/µs slew rate, 6.8 nV/√Hz input voltage noise, 6.4 mA per amplifier supply current, and operation on single supplies from 2.7 V to 12 V (or dual supplies). It is specified for operation over the -40 °C to +85 °C industrial temperature range.
Are both variants available in the same package?
Yes. Both AD8062ARMZ-R7 and AD8062ARM are offered in the 8-lead MSOP (Mini Small Outline Package). The package and pinout are identical; only the RoHS designation and reel packaging differ.
Which variant should be selected for a new RoHS-compliant design?
For new designs requiring RoHS compliance, select AD8062ARMZ-R7, which carries the RoHS-compliant "Z" designation and is supplied on 7-inch tape-and-reel for automated assembly. AD8062ARM should only be used where non-RoHS parts are explicitly permitted.
