Replacement verdict
Compatible functional replacement candidate
The AD8602DRZ and AD8602AR-REEL7 are functionally equivalent dual operational amplifiers from the same AD8602 family, sharing identical core electrical specifications. The primary distinction lies in package and packaging format, making the AD8602DRZ a viable functional replacement candidate for the AD8602AR-REEL7, provided the PCB footprint is verified for the SOIC-8 package.

Key electrical and mechanical differences between the two devices
| Parameter | AD8602DRZ | AD8602AR-REEL7 | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count matches for direct circuit substitution. |
| Supply Voltage Range | 2.7 V to 5.5 V | 2.7 V to 5.5 V | Identical operating supply range ensures compatibility with the same power rails. |
| Gain Bandwidth Product | 8.4 MHz | 8.4 MHz | Same bandwidth means equivalent AC performance and signal fidelity. |
| Input Offset Voltage (max) | 500 µV | 500 µV | Matching offset voltage ensures comparable DC accuracy in precision applications. |
| Input Bias Current | 1 pA (typ) | 1 pA (typ) | Very low bias current suits high-impedance sensor and photodiode interfaces equally. |
| Quiescent Current per Amplifier | 750 µA (typ) | 750 µA (typ) | Identical supply current keeps power budget unchanged when swapping parts. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount, tape and reel) | Same SOIC footprint allows drop-in replacement; only packaging/reel format differs for assembly handling. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +85 °C | The wider temperature rating of the DRZ version matters for harsh-environment or automotive-grade designs. |
| Slew Rate | 5 V/µs | 5 V/µs | Equal slew rate preserves large-signal transient response and stability. |

Frequently asked questions
What are the key differences between the AD8602DRZ and AD8602AR-REEL7?
Both parts are dual, precision, low-noise, CMOS operational amplifiers from Analog Devices with identical electrical specifications. The primary differences are package type and packaging format: the AD8602DRZ is supplied in an 8-lead SOIC package (R-8 suffix) in tube form, while the AD8602AR-REEL7 is supplied in an 8-lead SOIC package (R-8 suffix) in 7-inch tape-and-reel form for automated assembly.
Are the AD8602DRZ and AD8602AR-REEL7 electrically interchangeable?
Yes. Both devices share the same datasheet specifications, including 8 MHz gain bandwidth, 5.5 V/µs slew rate, 750 µV maximum offset voltage, 8 nV/√Hz input voltage noise, and 2.7 V to 5.5 V single-supply operation. They differ only in packaging format, not in electrical performance.
What package do the AD8602DRZ and AD8602AR-REEL7 use?
Both devices are offered in an 8-lead SOIC package (R-8). The AD8602DRZ is provided in tube packaging, while the AD8602AR-REEL7 is provided in 7-inch tape-and-reel packaging suitable for high-volume pick-and-place assembly.
Can the AD8602DRZ be used as a drop-in replacement for the AD8602AR-REEL7 on an existing PCB?
Yes, provided the PCB footprint is designed for the 8-lead SOIC package. Since both parts share the same package and pinout, the AD8602DRZ can be substituted for the AD8602AR-REEL7 in prototype or low-volume builds, while the AD8602AR-REEL7 is preferred for automated production lines using tape-and-reel feeders.
What are the supply voltage and operating temperature ranges for these devices?
Both the AD8602DRZ and AD8602AR-REEL7 operate from a single supply of 2.7 V to 5.5 V (or dual supplies of ±1.35 V to ±2.75 V) and are specified over the industrial temperature range of −40°C to +125°C.
Which part should be selected for high-volume automated assembly?
The AD8602AR-REEL7 is the appropriate choice for high-volume automated assembly because it is supplied in 7-inch tape-and-reel format compatible with standard SMT pick-and-place equipment. The AD8602DRZ, supplied in tubes, is better suited for prototyping, low-volume runs, or manual assembly.
Do the AD8602DRZ and AD8602AR-REEL7 share the same pinout?
Yes. Both devices use the standard 8-lead SOIC dual op-amp pinout: pin 1 = OUT A, pin 2 = −IN A, pin 3 = +IN A, pin 4 = V−, pin 5 = +IN B, pin 6 = −IN B, pin 7 = OUT B, and pin 8 = V+. This identical pinout supports direct substitution when the package footprint matches.
Are the AD8602DRZ and AD8602AR-REEL7 RoHS compliant?
Yes. Both the AD8602DRZ and AD8602AR-REEL7 are RoHS-compliant parts, as indicated by the "Z" suffix in the AD8602DRZ ordering code and the corresponding RoHS status of the AD8602AR-REEL7 in Analog Devices' product documentation.
