Replacement verdict
Compatible functional replacement candidate
The AD2S83APZ and AD2S83IP are functionally equivalent resolver-to-digital converters sharing identical core architecture, resolution, and tracking loop characteristics. The primary distinction lies in their operating temperature range and corresponding grade classification, making the AD2S83IP suitable for industrial temperature environments while the AD2S83APZ targets commercial applications. Both devices are interchangeable in circuits where the operating temperature remains within the commercial range, but the AD2S83IP should be selected for applications requiring extended temperature operation.

Frequently asked questions
What is the difference between the AD2S83APZ and the AD2S83IP?
The AD2S83APZ and AD2S83IP are both variable resolution resolver-to-digital converters from Analog Devices. The primary difference is their operating temperature range and corresponding grade: the AD2S83APZ is specified for the industrial temperature range of −40°C to +85°C, while the AD2S83IP is specified for the commercial temperature range of 0°C to +70°C. Both are offered in a 44-lead PLCC package.
Are the AD2S83APZ and AD2S83IP pin-compatible?
Yes. Both the AD2S83APZ and AD2S83IP are housed in the same 44-lead PLCC package and share the same pinout, so they are pin-compatible when the temperature grade is not a constraint.
Can the AD2S83APZ be used as a direct drop-in replacement for the AD2S83IP?
Electrically and mechanically, the AD2S83APZ can replace the AD2S83IP in the same 44-lead PLCC socket because the pinout and functional specifications are the same. However, the AD2S83APZ is rated for a wider industrial temperature range (−40°C to +85°C), so it may be used in applications where the AD2S83IP's 0°C to +70°C range is insufficient. Always verify the target design's thermal and electrical requirements against the manufacturer datasheet before substitution.
What is the resolution of the AD2S83APZ and AD2S83IP?
Both devices are variable resolution resolver-to-digital converters that support 10-bit, 12-bit, 14-bit, and 16-bit resolution, selectable by the user. The resolution is set via external components and configuration pins as described in the Analog Devices AD2S83 datasheet.
Do the AD2S83APZ and AD2S83IP require external components for operation?
Yes. Both the AD2S83APZ and AD2S83IP require external components, including a reference oscillator, filter components, and gain-setting resistors, to operate as resolver-to-digital converters. The required external component values depend on the selected resolution and bandwidth, as specified in the AD2S83 datasheet.
What is the input signal format for the AD2S83APZ and AD2S83IP?
Both devices accept resolver format input signals, typically consisting of sine and cosine signals from a resolver or synchro. The AD2S83 series is designed to convert these analog resolver signals into digital position and velocity data.
Are the AD2S83APZ and AD2S83IP RoHS compliant?
The AD2S83APZ is RoHS compliant, as indicated by the "Z" suffix in the part number, which denotes a lead-free/RoHS-compliant package. The AD2S83IP does not carry the "Z" suffix and is not RoHS compliant. Designers should confirm compliance status with the manufacturer's current documentation before use in RoHS-sensitive applications.
Which device should be selected for an industrial application with wide temperature variations?
For industrial applications with wide temperature variations, the AD2S83APZ is the appropriate choice because it is specified for the −40°C to +85°C industrial temperature range. The AD2S83IP is limited to the 0°C to +70°C commercial range and may not meet the thermal requirements of such applications.
