Key electrical and mechanical differences between the two devices
| Parameter | ADA4610-2ARZ | ADA4610-2ARZ-RL | Why it matters |
|---|---|---|---|
| Amplifier Type | JFET Input Operational Amplifier | JFET Input Operational Amplifier | Confirms both parts share the same core amplifier topology, ensuring functional equivalence in signal conditioning circuits. |
| Number of Channels | 2 | 2 | Both are dual-channel devices, so channel count and pinout compatibility are preserved for drop-in substitution. |
| Supply Voltage Range | ±4.5 V to ±15 V (dual supply) | ±4.5 V to ±15 V (dual supply) | Identical supply range ensures the replacement operates correctly in the same power rail configuration. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | Matching bandwidth guarantees the same AC performance and stability margins in the target circuit. |
| Input Offset Voltage (Max) | 0.5 mV | 0.5 mV | Equal offset voltage ensures DC accuracy is unchanged when swapping parts. |
| Input Bias Current (Typ) | 5 pA | 5 pA | Very low JFET input bias current is critical for high-impedance sensor and precision applications; identical values confirm equivalence. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Same package and footprint allow direct board replacement without layout changes. |
| Packaging / Delivery Form | Tube | Tape & Reel | The only functional difference is the shipping format; -RL denotes reel packaging suited to automated assembly, while the base part is typically tube-packed. |

Frequently asked questions
What is the difference between ADA4610-2ARZ and ADA4610-2ARZ-RL?
Both parts are the same ADA4610-2 dual low noise, precision JFET operational amplifier in an 8-lead SOIC package. The difference is packaging format: ADA4610-2ARZ is supplied in tube packaging, while ADA4610-2ARZ-RL is supplied in tape-and-reel packaging for automated assembly. Electrical and mechanical specifications are identical.
Are ADA4610-2ARZ and ADA4610-2ARZ-RL electrically identical?
Yes. Both order codes refer to the same die and package (8-lead SOIC, RoHS-compliant). The -RL suffix denotes tape-and-reel delivery only; it does not change electrical parameters, grade, or temperature range.
Can ADA4610-2ARZ-RL be used as a drop-in replacement for ADA4610-2ARZ?
Yes, from an electrical and footprint standpoint they are interchangeable because both are the same device in the same 8-lead SOIC package. The only practical consideration is assembly method: tape-and-reel (RL) is intended for pick-and-place production, while tube packaging is typically used for prototyping or low-volume hand assembly.
What package does the ADA4610-2ARZ family use?
The ADA4610-2ARZ and ADA4610-2ARZ-RL are both offered in an 8-lead SOIC package. The "ARZ" suffix indicates the SOIC package and RoHS compliance.
Why would a design choose the -RL tape-and-reel version over the tube version?
The -RL version is supplied on tape-and-reel, which is compatible with automated surface-mount pick-and-place equipment and supports higher-volume production. The tube version is more convenient for manual handling, prototyping, and small-quantity builds.
Do both order codes share the same operating temperature range and specifications?
Yes. Since both are the same ADA4610-2 device in the same SOIC package, they share identical datasheet specifications, including operating temperature range and electrical characteristics. Packaging format is the only difference between the two order codes.
