Replacement verdict
Compatible functional replacement candidate
The ADA4096-2WARMZ-RL is a viable functional replacement candidate for the ADA4004-2ARMZ in many dual op-amp applications, sharing the same MSOP-8 package and dual channel configuration. However, the ADA4096-2WARMZ-RL trades the ADA4004-2ARMZ's lower voltage noise and tighter offset voltage for over-the-top input capability and wider supply range, so designers must validate noise-sensitive and precision DC signal chains before substituting.

Key electrical and mechanical differences between the two devices
| Parameter | ADA4004-2ARMZ | ADA4096-2WARMZ-RL | Why it matters |
|---|---|---|---|
| Number of Amplifiers | 2 | 2 | Both are dual op-amps, so channel count is compatible for direct substitution. |
| Input Offset Voltage (Max) | 125 µV | 300 µV | Lower offset voltage improves DC precision; the ADA4004 offers tighter offset for high-accuracy signal chains. |
| Input Bias Current (Typ) | 90 nA | 0.3 nA | Much lower bias current in the ADA4096 reduces errors in high-impedance sensor and feedback networks. |
| Gain Bandwidth Product | 12 MHz | 1.5 MHz | Higher GBW supports wider signal bandwidth and faster settling; the ADA4004 is better for higher-frequency applications. |
| Slew Rate | 2.7 V/µs | 0.4 V/µs | Slew rate limits large-signal response speed; the ADA4004 handles faster transients than the ADA4096. |
| Supply Voltage Range | ±5 V to ±15 V (10 V to 30 V) | 3 V to 30 V (±1.5 V to ±15 V) | The ADA4096 supports lower single-supply operation, enabling use in low-voltage systems where the ADA4004 cannot operate. |
| Input Common-Mode Voltage Range | Rail-to-rail input not specified (limited CM range) | Rail-to-rail input (includes supply rails) | Rail-to-rail input in the ADA4096 allows sensing near supply rails, useful for high-side and low-side sensing. |
| Quiescent Current per Amplifier (Typ) | 1.7 mA | 0.065 mA | The ADA4096 draws far less supply current, making it preferable for battery-powered and low-power designs. |
| Operating Temperature Range | -40 °C to +125 °C | -40 °C to +125 °C | Both cover the industrial temperature range, so thermal compatibility is maintained for substitution. |
| Package | 8-Lead MSOP (RM) | 8-Lead MSOP (RM) | Identical package and pinout allow drop-in board replacement without layout changes. |

Frequently asked questions
What are the key differences between the ADA4004-2ARMZ and the ADA4096-2WARMZ-RL?
The ADA4004-2ARMZ is a dual precision low-noise bipolar operational amplifier specified for ±5 V to ±15 V supplies, while the ADA4096-2WARMZ-RL is a dual micropower, overvoltage-protected CMOS operational amplifier designed for 3 V to 30 V (or ±1.5 V to ±15 V) operation with input overvoltage protection up to 32 V beyond the supply rails. The ADA4004-2ARMZ targets low-noise precision signal conditioning, whereas the ADA4096-2WARMZ-RL targets robust, low-power industrial and automotive applications requiring input fault tolerance.
Are the ADA4004-2ARMZ and ADA4096-2WARMZ-RL pin-compatible?
Both devices are offered in 8-lead MSOP (RM) packages 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 ADA4004-2ARMZ and ADA4096-2WARMZ-RL share this pin configuration, but substitution requires verification of supply range, input common-mode range, and overvoltage protection behavior against the target design.
How do the supply voltage ranges of the ADA4004-2ARMZ and ADA4096-2WARMZ-RL compare?
The ADA4004-2ARMZ operates on a dual supply of ±5 V to ±15 V (10 V to 30 V total). The ADA4096-2WARMZ-RL operates on a single supply of 3 V to 30 V or a dual supply of ±1.5 V to ±15 V, giving it a wider low-voltage operating range suitable for 3.3 V and 5 V systems.
Which device offers input overvoltage protection?
The ADA4096-2WARMZ-RL features input overvoltage protection that allows the inputs to be driven up to 32 V beyond the supply rails without damage or phase inversion, making it suitable for harsh industrial environments. The ADA4004-2ARMZ does not specify this extended input overvoltage protection and should be operated within its specified input voltage range.
How do the noise characteristics of the ADA4004-2ARMZ and ADA4096-2WARMZ-RL differ?
The ADA4004-2ARMZ is a low-noise precision amplifier with a typical voltage noise density of approximately 1.8 nV/√Hz at 1 kHz, intended for low-level signal amplification. The ADA4096-2WARMZ-RL is a micropower CMOS amplifier with higher voltage noise density (on the order of tens of nV/√Hz), optimized for low power consumption rather than ultra-low noise.
How do the quiescent supply currents of the ADA4004-2ARMZ and ADA4096-2WARMZ-RL compare?
The ADA4096-2WARMZ-RL is a micropower device with a typical supply current of approximately 30 µA per amplifier, making it suitable for battery-powered and low-power systems. The ADA4004-2ARMZ draws a higher quiescent current (on the order of milliamperes per amplifier) in exchange for its low-noise, high-bandwidth precision performance.
Can the ADA4096-2WARMZ-RL replace the ADA4004-2ARMZ in a low-noise precision design?
Not directly in noise-critical designs. The ADA4004-2ARMZ provides significantly lower voltage noise density and higher bandwidth than the ADA4096-2WARMZ-RL. The ADA4096-2WARMZ-RL is preferable where low power and input overvoltage protection are required, but a replacement in a low-noise signal chain should be validated against the noise budget and bandwidth requirements of the application.
What are the operating temperature ranges for the ADA4004-2ARMZ and ADA4096-2WARMZ-RL?
The ADA4004-2ARMZ is specified over the industrial temperature range of −40 °C to +125 °C. The ADA4096-2WARMZ-RL is specified over the automotive temperature range of −40 °C to +125 °C, consistent with its W-grade automotive qualification.
