AD2S83IP-REEL

Overview

The AD2S83IP-REEL is a monolithic, variable resolution tracking resolver-to-digital converter manufactured by Analog Devices Inc. It converts resolver format input signals into parallel natural binary digital words using a ratiometric tracking conversion method. The device supports user-selectable resolutions of 10, 12, 14, or 16 bits via external control pins SC1 and SC2. It operates over an industrial temperature range of -40°C to +85°C and utilizes a 44-lead Plastic Leaded Chip Carrier (PLCC) package. The converter provides high noise immunity and tolerance for long leads, allowing remote placement from the resolver.

Feature Summary

• Ratiometric tracking conversion technique ensures continuous output position data without conversion delay and provides high noise immunity.
• User-configurable dynamic performance allows selection of bandwidth, maximum tracking rate, and velocity scaling through external resistor and capacitor values.
• Generates a precise analog signal proportional to velocity, eliminating the need for mechanical tachogenerators in servo systems.
• Features 3-state output pins compatible with 8-bit or 16-bit bus operations, supported by BYTE SELECT, ENABLE, and INHIBIT pins.

Applications

• DC and AC Servo Motor Control
• Process Control
• Numerical Control of Machine Tools
• Robotics Axis Control

Procurement Notes

Verify that the REEL suffix indicates tape-and-reel packaging rather than tube packaging when sourcing components. Confirm the specific IP variant accuracy rating of 8 arc minutes matches system requirements. Ensure ESD precautions are implemented during handling due to device sensitivity. Cross-reference the ordering guide to confirm availability of the reel configuration versus standard tube options.

Selection Notes

Select the AD2S83IP-REEL when industrial temperature operation (-40°C to +85°C) and 8 arc minute angular accuracy are required. Choose this model over the AP variant if specific reel packaging is necessary for automated assembly processes. Consider external component selection for R4 and R6 based on the desired resolution and tracking rate to optimize dynamic performance.

Part Context

The AD2S83 series includes variants such as the AD2S83AP and AD2S83IP, both offering 8 arc minute accuracy within the industrial temperature range. The IP designation specifically denotes the industrial grade version housed in a 44-lead PLCC package. This family serves as a high-precision solution for converting analog resolver signals into digital position data for motion control applications.
