Key electrical and mechanical differences between the two devices
| Parameter | AD2S82AHPZ | AD2S82ALP | Why it matters |
|---|---|---|---|
| Package / Case | 44-Pin PLCC (P-44A) | 44-Pin PLCC (P-44A) | The package type determines the PCB footprint and mounting style; identical packages allow drop-in replacement without layout changes. |
| Operating Temperature Range | -40°C to +85°C (industrial) | 0°C to +70°C (commercial) | The temperature grade affects reliability in harsh environments; industrial-grade parts are required for wide-temperature applications. |
| Resolution | 10-bit to 16-bit (selectable) | 10-bit to 16-bit (selectable) | Resolution determines the angular precision of the resolver-to-digital conversion; matching resolution ensures equivalent measurement accuracy. |
| Input Signal Type | Resolver (sine/cosine) | Resolver (sine/cosine) | The input signal type must match the sensor used; both parts accept standard resolver signals for direct interchangeability. |
| 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 ensure equivalent dynamic performance. |
| Supply Voltage | ±5 V (VDD/VSS), +5 V (VL) | ±5 V (VDD/VSS), +5 V (VL) | Supply voltage compatibility ensures the part can be powered from the same rails without additional regulation circuitry. |
| Output Interface | Parallel binary (natural binary) | Parallel binary (natural binary) | The output format must match the host processor interface; identical parallel outputs allow direct substitution. |
| Grade / Qualification | Industrial grade | Commercial grade | The grade indicates screening and environmental robustness; industrial parts are preferred for demanding or outdoor applications. |

Frequently asked questions
What are the AD2S82AHPZ and AD2S82ALP?
The AD2S82AHPZ and AD2S82ALP are variable resolution, monolithic resolver-to-digital converters (RDCs) from Analog Devices. They convert resolver signals into digital angle and velocity outputs. The AD2S82AHPZ is specified for operation over the commercial temperature range of 0°C to +70°C, while the AD2S82ALP is specified for the industrial temperature range of -40°C to +85°C.
What is the primary difference between the AD2S82AHPZ and AD2S82ALP?
The primary difference is the operating temperature range. The AD2S82AHPZ is rated for 0°C to +70°C (commercial), and the AD2S82ALP is rated for -40°C to +85°C (industrial). Both are functionally identical RDCs with the same resolution, accuracy, and input specifications when operated within their respective temperature ranges.
Are the AD2S82AHPZ and AD2S82ALP pin-compatible?
Yes. Both devices are offered in the same 44-lead plastic leaded chip carrier (PLCC) package and share an identical pinout. This allows the AD2S82ALP to be used as a drop-in replacement for the AD2S82AHPZ in applications requiring a wider operating temperature range, provided the rest of the system is rated for the industrial temperature range.
What is the resolution of the AD2S82AHPZ and AD2S82ALP?
Both devices provide variable resolution of 10, 12, 14, or 16 bits, selectable by the user via external pin programming. The resolution setting determines the digital output format and the corresponding accuracy and tracking rate specifications.
What input signal formats do the AD2S82AHPZ and AD2S82ALP accept?
Both RDCs accept standard resolver signals: sine and cosine inputs from a resolver or a synchro/resolver converter. They also require a reference input. The devices are designed to interface directly with resolvers and provide a digital representation of the shaft angle.
Can the AD2S82AHPZ be used in an industrial temperature environment?
No. The AD2S82AHPZ is specified only for the commercial temperature range of 0°C to +70°C. Operation outside this range is not guaranteed by the manufacturer. For industrial temperature applications (-40°C to +85°C), the AD2S82ALP must be used.
What are the accuracy specifications for the AD2S82AHPZ and AD2S82ALP?
Both devices offer accuracy of ±2 arc minutes at 16-bit resolution, ±4 arc minutes at 14-bit resolution, ±8 arc minutes at 12-bit resolution, and ±16 arc minutes at 10-bit resolution. These specifications are identical for both temperature grades when operated within their respective rated temperature ranges.
Are the AD2S82AHPZ and AD2S82ALP RoHS compliant?
Yes. Both the AD2S82AHPZ and AD2S82ALP are RoHS-compliant parts, as indicated by the "Z" suffix in the part number, which denotes lead-free/RoHS-compliant packaging. The "P" suffix indicates the PLCC package type.
