Replacement verdict
Compatible functional replacement candidate
The AD633JRZ and AD633ARZ are functionally interchangeable analog multiplier ICs sharing the same core architecture, pinout, and package. The AD633ARZ offers a tighter grade with improved linearity and offset specifications, making it a suitable upgrade path where enhanced accuracy is required, while the AD633JRZ remains adequate for standard-grade applications. Both devices are direct drop-in candidates, with the primary distinction being precision grade rather than functional compatibility.

Key electrical and mechanical differences between the two devices
| Parameter | AD633JRZ | AD633ARZ | Why it matters |
|---|---|---|---|
| Temperature Grade / Operating Temperature Range | 0°C to +70°C (commercial) | -40°C to +85°C (industrial) | The industrial-grade AD633ARZ supports a wider temperature range, making it suitable for harsher environments where the commercial-grade AD633JRZ may not be specified to operate. |
| Package / Mounting | 8-Lead SOIC (R-8) | 8-Lead SOIC (R-8) | Both use the same SOIC package footprint, so board-level physical substitutability is straightforward; the difference lies in the temperature grade rather than the package. |
| Function | Four-quadrant analog multiplier | Four-quadrant analog multiplier | Both parts perform the same core analog multiplication function, which is the primary basis for functional substitutability. |
| Supply Voltage Range | ±8 V to ±18 V (dual supply) | ±8 V to ±18 V (dual supply) | Identical supply requirements mean either part can be used in the same power rail design without changes. |
| Total Error (Multiplier Accuracy) | ±1.0% of full scale (typical max) | ±1.0% of full scale (typical max) | Matching accuracy specifications ensure comparable signal-processing performance in multiplier applications. |
| Bandwidth | 1 MHz (typical) | 1 MHz (typical) | Identical bandwidth means both parts handle the same frequency range for modulation and signal-mixing tasks. |
| Slew Rate | 20 V/µs (typical) | 20 V/µs (typical) | Equal slew rate ensures comparable dynamic response for fast-changing input signals. |
| Input Offset Voltage | ±5 mV (typical) | ±5 mV (typical) | Matching offset voltage keeps DC accuracy consistent between the two parts in precision multiplier circuits. |

Frequently asked questions
What are the key differences between the AD633JRZ and AD633ARZ?
Both are analog multiplier ICs from Analog Devices in an 8-lead SOIC package. The primary difference is the specified operating temperature range and corresponding grade: the AD633JRZ is specified for 0°C to +70°C (commercial grade), while the AD633ARZ is specified for −40°C to +85°C (industrial grade). Electrical performance specifications are otherwise similar per the datasheet.
Are the AD633JRZ and AD633ARZ pin-compatible?
Yes. Both devices are offered in the same 8-lead SOIC (R-8) package with identical pin functions, so they are pin-compatible and share the same PCB land pattern.
Can the AD633JRZ be used as a direct substitute for the AD633ARZ?
Only if the application's ambient temperature stays within 0°C to +70°C. The AD633JRZ is not specified for operation below 0°C or above +70°C, so it should not replace the AD633ARZ in designs requiring the industrial −40°C to +85°C range.
What is the functional block of the AD633?
The AD633 is a four-quadrant analog multiplier that includes a high-impedance differential X and Y input stage, a multiplier core, and a summing amplifier with a laser-trimmed 10 V reference, providing the output function W = (X1 − X2)(Y1 − Y2)/10 V + Z.
What supply voltage does the AD633JRZ and AD633ARZ require?
Both devices operate from dual supplies of ±8 V to ±18 V per the datasheet, with ±15 V being the typical operating condition for specified performance.
Do the AD633JRZ and AD633ARZ differ in accuracy specifications?
No. Per the Analog Devices datasheet, both the J and A grades share the same core accuracy specifications, including total error, nonlinearity, and output offset, at the specified test conditions; the grades differ in guaranteed temperature range rather than in the multiplier accuracy limits.
Which grade should be selected for an industrial temperature environment?
The AD633ARZ should be selected for industrial environments because it is specified over −40°C to +85°C, whereas the AD633JRZ is limited to 0°C to +70°C.
