Replacement verdict
Compatible functional replacement candidate
The ADA4622-2ARZ and ADA4610-2ARZ-RL are both dual, low-noise, precision JFET-input operational amplifiers in the same 8-lead SOIC package, making the ADA4622-2ARZ a viable functional replacement candidate for the ADA4610-2ARZ-RL in many designs. However, the two devices differ in supply voltage range, input bias current, and bandwidth, so the replacement should be validated against the specific application's supply rails, input impedance requirements, and AC performance targets before adoption.

Key electrical and mechanical differences between the two devices
| Parameter | ADA4622-2ARZ | ADA4610-2ARZ-RL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count is compatible for drop-in use in dual-channel circuits. |
| Gain Bandwidth Product (GBP) | 8 MHz | 16 MHz | GBP determines the maximum usable frequency for a given closed-loop gain; the ADA4610 offers roughly twice the bandwidth. |
| Input Offset Voltage (max) | 0.35 mV | 1 mV | Lower offset voltage reduces DC error in precision signal chains; the ADA4622 is tighter in this respect. |
| Input Bias Current (typ) | 1 pA | 5 pA | Very low bias current is critical for high-impedance sensor and photodiode front-ends; both are excellent but the ADA4622 is lower. |
| Supply Voltage Range | 4.5 V to 30 V (±2.25 V to ±15 V) | 4.5 V to 30 V (±2.25 V to ±15 V) | Identical supply range means both can operate from the same rails without circuit redesign. |
| Input Voltage Noise Density (1 kHz) | 12 nV/√Hz | 7.5 nV/√Hz | Lower voltage noise improves SNR in low-level signal amplification; the ADA4610 is quieter. |
| Quiescent Current per Amplifier (typ) | 0.75 mA | 1.6 mA | Quiescent current affects power budget in portable and battery-powered designs; the ADA4622 draws less. |
| Slew Rate | 23 V/µs | 25 V/µs | Slew rate limits large-signal bandwidth and settling; values are close, so dynamic behavior is broadly similar. |
| Package / Mounting | 8-Lead SOIC (surface mount) | 8-Lead SOIC (surface mount, tape and reel) | Same package footprint allows direct PCB substitution; the -RL suffix denotes tape-and-reel packaging for automated assembly. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Identical temperature ratings ensure both meet the same environmental requirements in industrial applications. |

Frequently asked questions
What are the key differences between the ADA4622-2ARZ and ADA4610-2ARZ-RL?
The ADA4622-2ARZ is a dual, low-bias-current, rail-to-rail output JFET-input operational amplifier from Analog Devices specified for a supply voltage range of ±5 V to ±15 V (10 V to 30 V total) with a typical input bias current of 1 pA and a gain bandwidth product of 8 MHz. The ADA4610-2ARZ-RL is a dual, low-noise, low-input-bias-current JFET-input op amp from Analog Devices specified for ±4.5 V to ±15 V (9 V to 30 V total) supplies with a typical input bias current of 5 pA and a gain bandwidth product of 16 MHz. The ADA4622-2 emphasizes lower input bias current and lower voltage noise, while the ADA4610-2 offers higher bandwidth and faster slew rate.
Are the ADA4622-2ARZ and ADA4610-2ARZ-RL pin-compatible?
Yes. Both devices are offered in the same 8-lead SOIC package (the "ARZ" suffix denotes the SOIC package in Analog Devices nomenclature), and both use the standard 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, pin 8 = V+. This allows board-level interchangeability, but electrical differences must still be validated for the target design.
How do the input bias currents of the ADA4622-2ARZ and ADA4610-2ARZ-RL compare?
The ADA4622-2ARZ has a typical input bias current of 1 pA (maximum specified in the low-picoamp range at 25°C per the datasheet), making it suitable for high-impedance sensor and photodiode interfaces. The ADA4610-2ARZ-RL has a typical input bias current of 5 pA. Both are JFET-input devices, but the ADA4622-2 provides the lower bias current of the two.
Which device offers higher bandwidth and slew rate?
The ADA4610-2ARZ-RL provides a gain bandwidth product of 16 MHz and a slew rate of 25 V/µs, whereas the ADA4622-2ARZ provides a gain bandwidth product of 8 MHz and a slew rate of 20 V/µs. For applications requiring faster signal handling, the ADA4610-2 is the higher-bandwidth option.
How do the voltage noise specifications differ between the two parts?
The ADA4622-2ARZ specifies a typical input voltage noise density of 12 nV/√Hz at 1 kHz, while the ADA4610-2ARZ-RL specifies a typical input voltage noise density of 8 nV/√Hz at 1 kHz. The ADA4610-2 therefore offers lower voltage noise, which can be advantageous in low-level signal amplification.
What supply voltage ranges do the ADA4622-2ARZ and ADA4610-2ARZ-RL support?
The ADA4622-2ARZ operates from a total supply voltage of 10 V to 30 V (±5 V to ±15 V), while the ADA4610-2ARZ-RL operates from a total supply voltage of 9 V to 30 V (±4.5 V to ±15 V). Both support rail-to-rail output swing, but the ADA4610-2 can operate at a slightly lower minimum supply of ±4.5 V.
Can the ADA4622-2ARZ and ADA4610-2ARZ-RL be used interchangeably in existing designs?
Because both are dual JFET-input op amps in the same 8-lead SOIC package with the same pinout, they are physically interchangeable. However, they are not electrically identical: gain bandwidth product (8 MHz vs 16 MHz), slew rate (20 V/µs vs 25 V/µs), input bias current (1 pA vs 5 pA), voltage noise (12 nV/√Hz vs 8 nV/√Hz), and minimum supply voltage (±5 V vs ±4.5 V) differ. A substitution should only be made after verifying stability, compensation, and performance against the manufacturer datasheets for the specific circuit.
What are the operating temperature ranges for these two amplifiers?
Both the ADA4622-2ARZ and ADA4610-2ARZ-RL are specified for the industrial temperature range of -40°C to +125°C, as stated in their respective Analog Devices datasheets. This makes both devices suitable for industrial and automotive-adjacent signal conditioning applications within that range.
