Replacement verdict
Compatible functional replacement candidate
The AD2S83APZ and AD2S82AKP are both monolithic resolver-to-digital converters from Analog Devices sharing the same 44-terminal J-lead ceramic package and core R/D conversion architecture, making the AD2S83APZ a viable functional replacement candidate for the AD2S82AKP in many resolver interface designs. However, the AD2S83APZ offers a higher maximum tracking rate and an extended operating temperature range, while the AD2S82AKP provides a higher resolution option, so designers must validate the specific resolution, bandwidth, and velocity specifications required by their application before substituting one for the other.

Key electrical and mechanical differences between the two devices
| Parameter | AD2S83APZ | AD2S82AKP | Why it matters |
|---|---|---|---|
| Resolution (bits) | 10, 12, 14, 16 (user selectable) | 10, 12, 14, 16 (user selectable) | Resolution determines the angular precision of the resolver-to-digital conversion; both support the same selectable resolutions, so substitutability is unaffected here. |
| Input Signal Type | Resolver (sine/cosine) | Resolver (sine/cosine) | Both devices interface with resolver signals, so the sensor interface is compatible for direct substitution. |
| Tracking Rate (max) | 1040 rps | 1040 rps | Maximum tracking rate defines how fast the converter can follow changing resolver angles; identical rates mean equivalent dynamic performance. |
| Supply Voltage | ±5 V, ±12 V (dual supply) | ±5 V, ±12 V (dual supply) | Supply requirements must match the host system rails; identical supplies simplify board-level replacement. |
| Package / Mounting | 44-Lead PLCC (PZ suffix) | 44-Lead PLCC (KP suffix) | Package and pinout determine physical and footprint compatibility; both are 44-lead PLCC, enabling drop-in replacement. |
| Operating Temperature Range | -40°C to +85°C (industrial) | 0°C to +70°C (commercial) | The wider industrial range of the AD2S83APZ allows use in harsher environments, while the AD2S82AKP is limited to commercial conditions. |
| Velocity Output | Analog velocity signal available | Analog velocity signal available | Velocity output supports motion control loops; both provide it, so functional substitutability is maintained. |
| Data Interface | Parallel binary output | Parallel binary output | The digital output format must match the system's data bus; both use parallel binary, ensuring compatibility. |

Frequently asked questions
What are the AD2S83APZ and AD2S82AKP?
The AD2S83APZ and AD2S82AKP are variable resolution, monolithic resolver-to-digital converters (RDCs) from Analog Devices. They convert resolver signals into digital angle and velocity data for motion control and position feedback applications.
What is the maximum resolution of the AD2S83APZ and AD2S82AKP?
Both devices support up to 16-bit resolution, selectable among 10-, 12-, 14-, and 16-bit modes. Resolution is set by external logic inputs and associated components.
What are the key differences between the AD2S83APZ and AD2S82AKP?
The AD2S83APZ is specified for operation over the commercial temperature range of 0°C to +70°C, while the AD2S82AKP is specified over the industrial temperature range of −40°C to +85°C. Both are offered in a 44-lead PLCC package, but the AD2S83APZ is a Pb-free/RoHS-compliant version, whereas the AD2S82AKP is not Pb-free/RoHS-compliant.
Are the AD2S83APZ 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 in the same PCB footprint. However, the AD2S83APZ is Pb-free/RoHS-compliant, while the AD2S82AKP is not, so solder process compatibility must be verified.
What is the input signal requirement for the AD2S83APZ and AD2S82AKP?
Both devices accept resolver signals in the form of sine and cosine inputs. The reference input is typically 2 V rms to 4 V rms, and the signal inputs are nominally 2 V rms, with an input frequency range of 50 Hz to 20 kHz, as specified in the Analog Devices datasheet.
What is the velocity output format of the AD2S83APZ and AD2S82AKP?
Both devices provide an analog velocity output signal proportional to the rate of change of the resolver angle. The velocity output is a DC voltage with a scale factor and polarity that depend on the external component selection and configuration.
Can the AD2S83APZ and AD2S82AKP be used interchangeably in an existing design?
They are functionally equivalent and pin-compatible, but the AD2S83APZ is Pb-free/RoHS-compliant and rated for 0°C to +70°C, while the AD2S82AKP is not Pb-free/RoHS-compliant and is rated for −40°C to +85°C. Interchangeability depends on the required temperature range and soldering process, and must be validated against the specific application requirements.
What package do the AD2S83APZ and AD2S82AKP use?
Both devices are supplied in a 44-lead PLCC (Plastic Leaded Chip Carrier) package. The AD2S83APZ is the Pb-free/RoHS-compliant version of the same package, while the AD2S82AKP is the non-Pb-free version.
