Replacement verdict
Compatible functional replacement candidate
The ADA4610-2BRZ and ADA4610-2BRZ-RL are functionally identical dual operational amplifiers from the same manufacturer, differing only in packaging format. The ADA4610-2BRZ is supplied in tube packaging, while the ADA4610-2BRZ-RL is supplied in tape-and-reel packaging. Both parts share the same die, electrical specifications, package type, and temperature range, making them fully interchangeable for design and functional purposes. The only consideration is the assembly and handling format required by the production line.

Key electrical and mechanical differences between the two devices
| Parameter | ADA4610-2BRZ | ADA4610-2BRZ-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-chain designs. |
| Number of Channels | 2 | 2 | Dual-channel configuration must match for pin-compatible substitution in existing PCB layouts. |
| 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 environment. |
| Gain Bandwidth Product | 16 MHz | 16 MHz | GBW determines the achievable closed-loop bandwidth and must match for equivalent AC performance. |
| Input Offset Voltage (max) | 0.5 mV | 0.5 mV | Offset voltage directly affects DC accuracy; matching values preserve precision in instrumentation circuits. |
| Input Bias Current (typ) | 5 pA | 5 pA | Ultra-low JFET input bias current is critical for high-impedance sensor and photodiode applications. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount) | Same package and footprint guarantee drop-in physical compatibility on the PCB. |
| Packaging / Delivery Form | Tube | Tape and Reel | The only functional difference is the shipping format; reel packaging suits automated SMT assembly while tubes suit manual or low-volume handling. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Identical industrial temperature range ensures reliable operation in the same environmental conditions. |

Frequently asked questions
What is the difference between ADA4610-2BRZ and ADA4610-2BRZ-RL?
Both parts are the same ADA4610-2 dual precision JFET-input operational amplifier in an 8-lead SOIC package. The difference is packaging format: ADA4610-2BRZ is supplied in tube/tray packaging, while the -RL suffix denotes tape-and-reel packaging for automated assembly. Electrical and functional specifications are identical.
Are ADA4610-2BRZ and ADA4610-2BRZ-RL electrically identical?
Yes. Both variants share the same die and datasheet specifications, including low input bias current, low offset voltage, low noise, and rail-to-rail output. The -RL suffix only indicates tape-and-reel delivery, not a different silicon or grade.
What does the "BRZ" suffix indicate in ADA4610-2BRZ?
The "B" denotes the grade, "R" denotes the 8-lead SOIC package, and "Z" denotes RoHS-compliant lead finish. Both ADA4610-2BRZ and ADA4610-2BRZ-RL carry the same BRZ grade and package designation.
Can ADA4610-2BRZ and ADA4610-2BRZ-RL be used interchangeably in a design?
Yes, from an electrical and footprint standpoint they are interchangeable. The only practical consideration is the assembly process: -RL tape-and-reel is intended for automated pick-and-place lines, while the tube version suits manual or low-volume assembly.
What is the package and pinout of these devices?
Both parts are offered in an 8-lead SOIC package with the standard dual op-amp pinout: 1 OUT A, 2 -IN A, 3 +IN A, 4 V-, 5 +IN B, 6 -IN B, 7 OUT B, 8 V+. The pinout is identical between the tube and tape-and-reel variants.
Why would a designer choose the -RL tape-and-reel version?
The -RL version is supplied on tape and reel, which is compatible with automated surface-mount assembly equipment. It is typically selected for high-volume production where pick-and-place feeders are used, while the non-RL version is common for prototyping and low-volume builds.
Do both variants meet the same RoHS and qualification requirements?
Yes. Both ADA4610-2BRZ and ADA4610-2BRZ-RL carry the "Z" RoHS-compliant designation and are covered by the same manufacturer qualification and datasheet specifications. Packaging format does not affect compliance status.
