Replacement verdict
Compatible functional replacement candidate
The AD2S82ALPZ and AD2S82AJP are functionally equivalent resolver-to-digital converters sharing identical core specifications, including resolution, accuracy, and input signal characteristics. The primary distinction lies in their operating temperature range and package grade, making the AD2S82ALPZ a viable replacement for the AD2S82AJP in applications where the extended temperature range is not a strict requirement. Designers should verify thermal margins and mechanical fit before committing to a drop-in substitution.

Key electrical and mechanical differences between the two devices
| Parameter | AD2S82ALPZ | AD2S82AJP | Why it matters |
|---|---|---|---|
| Package / Case | 44-LCC (J-Lead) | 44-PLCC (Plastic Leaded Chip Carrier) | The physical package determines the PCB footprint, assembly process, and thermal characteristics; a different package means the parts are not drop-in replacements on the same board layout. |
| Mounting Type | Surface Mount | Surface Mount | Mounting style affects how the component is attached to the board; both being surface mount supports similar assembly, but package differences still prevent direct substitution. |
| Operating Temperature Range | -40°C to +85°C | 0°C to +70°C | The temperature grade defines the environments in which the device can reliably operate; the wider industrial range of the ALPZ allows use in harsher conditions than the commercial-grade AJP. |
| Resolution | 10-bit / 12-bit / 14-bit / 16-bit (selectable) | 10-bit / 12-bit / 14-bit / 16-bit (selectable) | Resolution determines the angular measurement precision of the resolver-to-digital converter; identical resolution options mean both parts offer the same measurement granularity. |
| Input Signal Type | Resolver (sin/cos) | Resolver (sin/cos) | The input signal type must match the sensor used in the system; both accept resolver signals, so they are functionally compatible at the signal interface level. |
| Supply Voltage | ±5 V (dual supply) | ±5 V (dual supply) | Supply voltage must match the system power rails; identical supply requirements mean both parts can operate from the same power design. |
| Output Interface | Parallel binary | Parallel binary | The output interface determines how the digital position data is read by the host controller; matching parallel outputs ensure the same interface logic can be used. |
| Tracking Rate | Up to 1040 rps (16-bit) | Up to 1040 rps (16-bit) | Tracking rate defines the maximum rotational speed the converter can follow without losing lock; identical rates mean equivalent dynamic performance in motion control applications. |
| Manufacturer | Analog Devices Inc. | Analog Devices Inc. | The manufacturer affects availability, documentation, and support; both being from Analog Devices ensures consistent quality and datasheet references. |

Frequently asked questions
What are the AD2S82ALPZ and AD2S82AJP?
The AD2S82ALPZ and AD2S82AJP are both variable resolution, monolithic resolver-to-digital (R/D) converters from Analog Devices. They convert resolver signals into digital angle and velocity outputs. The AD2S82ALPZ is specified over the commercial temperature range and is supplied in a 44-lead PLCC package, while the AD2S82AJP is specified over the industrial temperature range and is supplied in a 44-lead PLCC package.
What is the difference between the AD2S82ALPZ and AD2S82AJP?
The primary difference is the operating temperature range and corresponding grade. The AD2S82ALPZ is a commercial-grade device, while the AD2S82AJP is an industrial-grade device. Both are functionally equivalent R/D converters in the same 44-lead PLCC package, but the AD2S82AJP is tested and guaranteed over the industrial temperature range, whereas the AD2S82ALPZ is tested and guaranteed over the commercial temperature range.
Are the AD2S82ALPZ and AD2S82AJP pin-compatible?
Yes. Both devices are offered in the same 44-lead PLCC package and share the same pinout. This allows the AD2S82AJP to be used in place of the AD2S82ALPZ, or vice versa, provided the operating temperature requirements of the application are satisfied.
Can the AD2S82ALPZ and AD2S82AJP be used interchangeably?
They can be used interchangeably only if the application's operating temperature range is within the commercial temperature range specified for the AD2S82ALPZ. If the application requires operation over the industrial temperature range, the AD2S82AJP must be used. All other electrical and functional characteristics are equivalent between the two grades.
What is the resolution of the AD2S82ALPZ and AD2S82AJP?
Both the AD2S82ALPZ and AD2S82AJP are variable resolution R/D converters. The resolution is set by external components and can be configured for 10, 12, 14, or 16 bits. The resolution is not fixed by the device grade.
What are the key specifications of the AD2S82ALPZ and AD2S82AJP?
Both devices are monolithic resolver-to-digital converters with variable resolution (10, 12, 14, or 16 bits), a velocity output, and a maximum tracking rate that depends on the selected resolution. They operate from ±5 V and +5 V supplies and provide a digital angle output with a specified accuracy. For detailed electrical specifications, refer to the Analog Devices AD2S82A datasheet.
What package do the AD2S82ALPZ and AD2S82AJP use?
Both the AD2S82ALPZ and AD2S82AJP are supplied in a 44-lead PLCC (Plastic Leaded Chip Carrier) package. The package is identical for both grades.
What temperature range does the AD2S82ALPZ support?
The AD2S82ALPZ is specified for the commercial temperature range. For the exact temperature limits, consult the Analog Devices AD2S82A datasheet, as the commercial grade typically covers 0°C to +70°C.
What temperature range does the AD2S82AJP support?
The AD2S82AJP is specified for the industrial temperature range. For the exact temperature limits, consult the Analog Devices AD2S82A datasheet, as the industrial grade typically covers −40°C to +85°C.
