Replacement verdict
Compatible functional replacement candidate
The AD2S82AHPZ and AD2S82AKP are functionally equivalent resolver-to-digital converters from the same Analog Devices AD2S82A series, sharing identical resolution, input signal compatibility, and output interface characteristics. The primary distinction lies in the specified operating temperature range, where the AD2S82AHPZ offers a wider industrial-grade range compared to the AD2S82AKP. For applications operating within the commercial temperature envelope, the AD2S82AKP serves as a viable functional substitute; however, designs requiring extended temperature operation should validate thermal margins before substituting the AD2S82AHPZ with the AD2S82AKP.

Key electrical and mechanical differences between the two devices
| Parameter | AD2S82AHPZ | AD2S82AKP | Why it matters |
|---|---|---|---|
| Operating Temperature Range | -40°C to +85°C | 0°C to +70°C | Determines the environments in which the device can reliably operate; the HPZ grade supports industrial temperature ranges while the KP grade is limited to commercial ranges. |
| Package / Case | 44-Pin PLCC (Plastic Leaded Chip Carrier) | 44-Pin PLCC (Plastic Leaded Chip Carrier) | Package type affects PCB footprint, thermal performance, and assembly process compatibility. |
| Temperature Grade | Industrial (H grade) | Commercial (K grade) | The temperature grade indicates the qualified operating range and reliability level; industrial grades are screened for harsher conditions. |
| Resolution | 16-bit | 16-bit | Resolution determines the angular measurement precision of the resolver-to-digital converter. |
| Supply Voltage | ±5 V (dual supply) | ±5 V (dual supply) | Supply voltage must match the system power rails for proper operation and signal integrity. |
| Tracking Rate | Up to 1040 rps (revolutions per second) | Up to 1040 rps (revolutions per second) | Maximum tracking rate defines the highest rotational speed the converter can follow without losing lock. |
| Input Signal Type | Resolver (sin/cos) | Resolver (sin/cos) | Defines the sensor interface compatibility; both parts accept standard resolver signals. |
| Accuracy | ±8 arc minutes | ±8 arc minutes | Accuracy specifies the maximum angular error, critical for position control loop performance. |
| Manufacturer Part Status | Active | Active | Part lifecycle status affects long-term availability and suitability for new designs. |

Frequently asked questions
What are the AD2S82AHPZ and AD2S82AKP?
The AD2S82AHPZ and AD2S82AKP are variable resolution, monolithic resolver-to-digital converters (RDCs) from Analog Devices. They convert resolver signals into digital angle and velocity outputs for motion control and position sensing applications.
What is the difference between the AD2S82AHPZ and AD2S82AKP?
The primary difference is the operating temperature range and corresponding grade. The AD2S82AHPZ is specified for the commercial temperature range of 0°C to +70°C, while the AD2S82AKP is specified for the industrial temperature range of -40°C to +85°C. Both are offered in a 44-lead PLCC package.
Are the AD2S82AHPZ and AD2S82AKP pin-compatible?
Yes. Both devices are housed in the same 44-lead PLCC package and share the same pinout, allowing them to be used interchangeably on a common PCB footprint when the operating temperature requirements are met.
Can the AD2S82AHPZ be used as a direct replacement for the AD2S82AKP?
In applications where the ambient temperature remains within 0°C to +70°C, the AD2S82AHPZ can function as a direct replacement for the AD2S82AKP because they share the same package, pinout, and functional specifications. However, for designs requiring operation below 0°C or above +70°C, the AD2S82AKP must be used.
What is the resolution of the AD2S82AHPZ and AD2S82AKP?
Both devices offer selectable resolution of 10, 12, 14, or 16 bits. The resolution is configured via external pin programming, allowing designers to optimize for accuracy or conversion speed as required by the application.
What are the key performance specifications shared by the AD2S82AHPZ and AD2S82AKP?
Both converters feature a maximum tracking rate of 1,040,000 RPM at 10-bit resolution, programmable dynamic characteristics, and a velocity output signal. They also provide a ±10 arc-minute accuracy specification at 12-bit resolution and operate from ±5 V analog supplies with a +5 V digital supply.
Which applications are suitable for the AD2S82AHPZ versus the AD2S82AKP?
The AD2S82AHPZ is suitable for commercial and laboratory environments where temperatures stay within 0°C to +70°C, such as benchtop test equipment and controlled industrial settings. The AD2S82AKP is intended for industrial and automotive applications that require reliable operation over the -40°C to +85°C range, including factory automation, robotics, and outdoor motion control systems.
Do the AD2S82AHPZ and AD2S82AKP require external components for operation?
Yes. Both devices require external passive components, including resistors and capacitors, for setting loop compensation, reference frequency, and filter characteristics. The manufacturer datasheet provides recommended values and configuration guidelines for each resolution setting.
