Key electrical and mechanical differences between the two devices
| Parameter | AD8062ARMZ | AD8062ARM | Why it matters |
|---|---|---|---|
| Amplifier Type | Voltage Feedback | Voltage Feedback | Both are voltage-feedback op-amps, so the feedback topology and compensation behavior are the same. |
| Number of Channels | 2 | 2 | Dual-channel configuration determines package pinout and board layout compatibility. |
| Gain Bandwidth Product | 300 MHz | 300 MHz | GBW sets the achievable closed-loop bandwidth and is critical for high-speed signal processing. |
| Slew Rate | 650 V/µs | 650 V/µs | Slew rate limits large-signal bandwidth and distortion performance in fast transients. |
| Input Offset Voltage | 1 mV (typ) | 1 mV (typ) | Offset voltage affects DC accuracy and error budget in precision signal chains. |
| Supply Voltage Range | 2.7 V to 12 V | 2.7 V to 12 V | Supply range determines compatibility with single-supply and split-supply system rails. |
| Supply Current per Channel | 6.5 mA (typ) | 6.5 mA (typ) | Quiescent current impacts power budget and thermal design in portable and dense systems. |
| Package / Mounting | 8-Lead MSOP, Surface Mount | 8-Lead MSOP, Surface Mount | Identical package and mounting ensure drop-in PCB footprint compatibility. |
| RoHS / Lead-Free Status | RoHS Compliant, Lead-Free | Non-RoHS, Contains Lead | The "Z" suffix denotes lead-free/RoHS compliance, which affects regulatory compliance and solder process requirements. |

Frequently asked questions
What is the difference between the AD8062ARMZ and the AD8062ARM?
The AD8062ARMZ and AD8062ARM are the same dual, low-cost, high-speed operational amplifier from Analog Devices. The suffix difference is packaging/lead finish: the AD8062ARMZ is the RoHS-compliant, lead-free (Pb-free) version in an 8-lead MSOP, while the AD8062ARM is the non-RoHS version of the same device in the same 8-lead MSOP package.
Are the AD8062ARMZ and AD8062ARM electrically and functionally identical?
Yes. Both parts share the same datasheet specifications for the AD8062: dual operational amplifier, 300 MHz -3 dB bandwidth, 650 V/µs slew rate, 8 nV/√Hz input voltage noise, 2.7 V to 8 V single-supply (or ±1.35 V to ±4 V dual-supply) operation, and rail-to-rail output. The only documented difference is the RoHS/lead-finish designation.
Can the AD8062ARMZ be used as a drop-in replacement for the AD8062ARM?
Yes, in most cases. Both are offered in the identical 8-lead MSOP package with the same pinout, so the PCB land pattern and pin functions are unchanged. The AD8062ARMZ is the Pb-free, RoHS-compliant variant and is generally the preferred replacement where RoHS compliance is required; verify any assembly-process or documentation requirements before substituting.
What package do the AD8062ARMZ and AD8062ARM use?
Both devices are supplied in the 8-lead MSOP (Mini Small Outline Package), designated by the "RM" suffix in the part number. The "Z" suffix on the AD8062ARMZ indicates the RoHS-compliant, lead-free finish.
What are the key AC specifications of the AD8062?
Per the Analog Devices AD8062 datasheet, the device provides a -3 dB bandwidth of 300 MHz (G = +1), a slew rate of 650 V/µs, and a settling time of 32 ns to 0.1%. These specifications apply equally to the AD8062ARMZ and AD8062ARM.
What supply voltage range does the AD8062 support?
The AD8062 operates from a single supply of 2.7 V to 8 V, or from dual supplies of ±1.35 V to ±4 V. This applies to both the AD8062ARMZ and AD8062ARM.
Is the AD8062ARMZ RoHS compliant while the AD8062ARM is not?
Yes. The "Z" suffix in the AD8062ARMZ denotes the RoHS-compliant, lead-free (Pb-free) package finish per Analog Devices part-numbering convention. The AD8062ARM is the non-RoHS version. Designers requiring RoHS compliance should specify the AD8062ARMZ.
