Replacement verdict
Compatible functional replacement candidate
The ADA4075-2ARZ and ADA4062-2ARZ are both dual low-power operational amplifiers in the same 8-lead SOIC package, making them a viable functional replacement candidate. However, the ADA4075-2ARZ offers higher bandwidth and slew rate, while the ADA4062-2ARZ provides lower input bias current and lower supply current, so the substitution should be validated against the specific application's AC performance and power budget requirements.

Key electrical and mechanical differences between the two devices
| Parameter | ADA4075-2ARZ | ADA4062-2ARZ | Why it matters |
|---|---|---|---|
| Input Voltage Noise Density | 11 nV/√Hz (typ, at 1 kHz) | 36 nV/√Hz (typ, at 1 kHz) | Lower noise density improves signal-to-noise ratio in precision and low-level signal applications. |
| Gain Bandwidth Product | 6.5 MHz (typ) | 1.4 MHz (typ) | GBW determines the maximum frequency at which the amplifier can provide useful gain. |
| Input Bias Current | 30 nA (typ) | 2 pA (typ) | Low bias current is critical for high-impedance sensor and precision DC applications. |
| Supply Current per Amplifier | 1.3 mA (typ) | 0.25 mA (typ) | Supply current affects power budget, especially in battery-powered or portable designs. |
| Slew Rate | 2.5 V/µs (typ) | 0.5 V/µs (typ) | Slew rate limits large-signal bandwidth and affects transient response and distortion. |
| Input Offset Voltage | 125 µV (max) | 250 µV (max) | Offset voltage directly contributes to DC error and affects precision in measurement circuits. |
| Supply Voltage Range | ±4.5 V to ±18 V (dual) | ±4 V to ±15 V (dual) | The supply range determines compatibility with the system power rails and headroom. |

Frequently asked questions
What are the key differences between the ADA4075-2ARZ and ADA4062-2ARZ operational amplifiers?
The ADA4075-2ARZ is a dual low-noise, low-power JFET-input op amp with a typical input voltage noise density of 11 nV/√Hz at 1 kHz and a typical supply current of 1.3 mA per amplifier. The ADA4062-2ARZ is a dual low-power JFET-input op amp with a typical input voltage noise density of 36 nV/√Hz at 1 kHz and a typical supply current of 200 µA per amplifier. The ADA4075-2ARZ targets lower-noise applications, while the ADA4062-2ARZ targets lower-power applications.
Are the ADA4075-2ARZ and ADA4062-2ARZ pin-compatible?
Yes. Both devices are offered in the same 8-lead SOIC package (ARZ suffix) with the standard dual op amp pinout, so they are pin-compatible when both are supplied in that package.
What are the supply voltage ranges for the ADA4075-2ARZ and ADA4062-2ARZ?
Both the ADA4075-2ARZ and ADA4062-2ARZ operate from dual supplies of ±4.5 V to ±15 V (or single supplies of 9 V to 30 V), as specified in their respective Analog Devices datasheets.
Which device has lower input voltage noise, the ADA4075-2ARZ or the ADA4062-2ARZ?
The ADA4075-2ARZ has lower input voltage noise, with a typical value of 11 nV/√Hz at 1 kHz, compared with a typical 36 nV/√Hz at 1 kHz for the ADA4062-2ARZ.
Which device consumes less supply current, the ADA4075-2ARZ or the ADA4062-2ARZ?
The ADA4062-2ARZ consumes less supply current, with a typical value of 200 µA per amplifier, compared with a typical 1.3 mA per amplifier for the ADA4075-2ARZ.
What are the gain bandwidth products of the ADA4075-2ARZ and ADA4062-2ARZ?
The ADA4075-2ARZ has a typical gain bandwidth product of 6.5 MHz, while the ADA4062-2ARZ has a typical gain bandwidth product of 1.5 MHz, per the Analog Devices datasheets.
Can the ADA4062-2ARZ be used as a drop-in replacement for the ADA4075-2ARZ?
They are pin-compatible in the 8-lead SOIC package, but they are not electrically equivalent. The ADA4062-2ARZ has lower supply current but higher input voltage noise and lower gain bandwidth than the ADA4075-2ARZ, so a replacement should only be made after verifying that the reduced noise and bandwidth performance still meets the application requirements.
