Key electrical and mechanical differences between the two devices
| Parameter | AD8602DRZ | AD8602AR | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count matches for direct substitution. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Identical operating supply range ensures compatibility in the same circuit rails. |
| Gain Bandwidth Product | 8.4 MHz | 8.4 MHz | Same bandwidth means AC performance and stability are preserved. |
| Input Offset Voltage (max) | 500 µV | 500 µV | Matching offset voltage keeps DC accuracy equivalent between parts. |
| Input Bias Current | 1 pA (typ) | 1 pA (typ) | Very low bias current suits high-impedance sensor interfaces equally. |
| Quiescent Current per Amplifier | 750 µA (typ) | 750 µA (typ) | Same supply current keeps power budget unchanged. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Package and footprint must match for board-level drop-in replacement. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +85 °C | The DRZ grade supports a wider temperature range, which matters for harsh-environment designs. |
| Grade / Qualification | Automotive/industrial grade (extended temp) | Standard commercial/industrial grade | Grade differences affect guaranteed specs over temperature and suitability for automotive use. |

Frequently asked questions
What are the key differences between the AD8602DRZ and AD8602AR?
The AD8602DRZ and AD8602AR are both dual, precision, low-noise operational amplifiers from Analog Devices. The primary difference is the package and temperature grade: the AD8602DRZ is supplied in an 8-lead SOIC (R-8) package specified over the −40°C to +125°C industrial temperature range, while the AD8602AR is supplied in an 8-lead SOIC (R-8) package specified over the −40°C to +85°C temperature range. Both share the same core electrical specifications.
Are the AD8602DRZ and AD8602AR electrically identical?
Yes. Both parts are members of the same AD8602 family and share the same datasheet electrical characteristics, including typical 8 MHz gain bandwidth, 5 V/µs slew rate, low input offset voltage, and rail-to-rail input/output operation. The distinguishing factor is the guaranteed temperature range and the associated package/ordering code, not the amplifier core.
Can the AD8602DRZ be used as a drop-in replacement for the AD8602AR?
In most applications the two parts are functionally interchangeable because they share the same 8-lead SOIC footprint and pinout. However, the AD8602DRZ is specified over a wider −40°C to +125°C range, so it can replace the AD8602AR where the ambient temperature stays within the AD8602AR's −40°C to +85°C rating. Always verify the target design's thermal and electrical margins against the manufacturer datasheet before substitution.
What is the operating temperature range of each part?
The AD8602DRZ is specified for operation from −40°C to +125°C. The AD8602AR is specified for operation from −40°C to +85°C. Designs that must operate above +85°C should use the AD8602DRZ or another part rated for the required range.
Do both parts come in the same package and pinout?
Yes. Both the AD8602DRZ and AD8602AR are offered in the 8-lead SOIC (R-8) package with the same pin configuration, so PCB land patterns and pin assignments are compatible. The suffix letters denote ordering/grade differences rather than a different package family.
What are the key AC and DC specifications shared by both parts?
Per the Analog Devices AD8602 datasheet, both parts feature a typical gain bandwidth of 8 MHz, a slew rate of 5 V/µs, low input offset voltage, low input bias current, and rail-to-rail input and output swing. They operate from a single supply of 2.7 V to 5.5 V (or dual supplies) and are intended for precision, low-noise signal conditioning. Confirm exact limits against the current datasheet revision for the specific grade.
Which part should be selected for a design that must operate up to +125°C?
The AD8602DRZ should be selected, because its specified operating temperature range extends to +125°C, whereas the AD8602AR is only specified to +85°C. Using the AD8602AR above +85°C would exceed its guaranteed operating conditions.
Are the AD8602DRZ and AD8602AR RoHS compliant?
Both parts are available in RoHS-compliant versions as indicated by their ordering codes and Analog Devices' product documentation. Because compliance can depend on the specific ordering code and date code, verify the RoHS status on the manufacturer datasheet or an authorized distributor listing for the exact part number before finalizing a design or procurement decision.
